Vishay standard rectifiers deliver high current ratings to 12 A in new Power DFN series DFN6546A package. September 16, 2026 Vishay Intertechnology, introduced four new series of surface-mount standard rectifiers that are the industry's first such devices in the low profile DFN6546A package with wettable flanks. Providing space-saving solutions for power line polarity protection and rail to rail protection in commercial, industrial, and automotive applications, the 5 A SE50N6x, 8 A SE80N6x, 10 A SE100N6x, and 12 A SE120N6x are each available with reverse voltages of 200 V, 400 V, and 600 V, and are offered in AEC-Q101 qualified versions. The latest package in Vishay's new Power DFN family, the DFN6546A features a compact 6.5 mm by 4.6 mm footprint and an extremely low typical height of 0.88 mm, allowing the Vishay General Semiconductor rectifiers released today to make more efficient use of PCB space. At the same time, the devices' advanced construction and die placement technology allow for a higher copper content and larger chip sizes, resulting in improved thermal performance, higher current ratings, and forward surge current capability. Compared to solutions in the SMPC (TO-277A) package with the same footprint, the SE50N6x, SE80N6x, SE100N6x, and SE120N6x deliver a 10 % lower profile, 20 % higher current ratings, and 82 % higher forward surge capability. Featuring an oxide planar chip junction design, the rectifiers offer typical reverse leakage current less than 0.1 μA, while their low forward voltage drops down to 0.77 V reduces power losses to improve efficiency. The devices operate over a wide temperature range from -55 °C to +175 °C, and provide ESD capability in compliance with IEC 61000-4-2, air discharge mode. The wettable flanks of their DFN6546A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection. Ideal for automated placement, the rectifiers offer an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 °C. The devices are RoHS-compliant and halogen-free. Device specification table: Samples and production quantities of the new surface-mount standard rectifiers in the DFN6546A package are available now, with lead times of eight weeks.

Vishay Intertechnology has introduced a new series of bidirectional XClampR flat clamping transient voltage suppressors in the surface-mount DO-218AC package. The XFD11KxxCA series represents the industry's first devices to provide peak pulse power dissipation comparable to 11 kW conventional TVS at 10/1000 μs whilst maintaining a low clamping ratio close to 1.0 for high power density. The series features 15 devices in both commercial-grade and AEC-Q101 qualified versions. Compared to conventional devices in DO-218-compatible packages, the XFD11KxxCA series delivers approximately 1.6 times higher peak pulse current — up to 207.1 A at 10/1000 μs. The TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. Applications include automotive systems, energy storage, industrial controls, and telecommunications equipment. Samples and production quantities are available now.

Vishay introduces 16-bit inductive encoder for motor-adjacent position sensing. Reading Time: 6 mins read Vishay Intertechnology has introduced the RAIK045I MP, a single-turn, off-axis inductive rotary position sensor encoder with 16-bit resolution, >= 14-bit repeatability, and an SPI output, targeted at industrial motion-control applications operating near electric motors. Vishay states the inductive rotary position sensor encoder is immune to external magnetic fields, which distinguishes it from Hall-effect-based encoders used in similar duty. It is positioned as a cost-effective alternative to higher-performance encoder solutions for robotics, motor drives, and conveyor systems. What changed. * Vishay has released a new medium-precision (MP) variant within the RAIK045I inductive kit encoder family, document number 32647, revision dated 23-Apr-2026. * The manufacturer states the sensor uses inductive rather than magnetic (Hall-effect) sensing, which it says makes it insensitive to external magnetic fields, moisture, and airborne pollution. * Key confirmed ratings: 16-bit resolution, >= 14-bit repeatability, absolute accuracy >= 10 bits (0.35°), and rotation speeds up to 10,000 rpm. * Samples and production quantities are stated as available now, with a lead time of 16 weeks. Key technical data. Engineering implications. The datasheet distinguishes accuracy at 25°C (>= 10 bits, 0.35°, typical 0.22°) from the additional +/-0.16° temperature derating specified across -40°C to +105°C. For design engineers, this means the worst-case positioning error budget over the full temperature range must combine both figures rather than relying on the room-temperature accuracy number alone. Resolution (16 bits) and repeatability (>= 14 bits) are also separate parameters: resolution defines the smallest reportable angle step, while repeatability describes how consistently the sensor reproduces a reading at the same physical position - accuracy is a distinct, generally coarser, specification. The manufacturer notes the sensor does not integrate protection against surge-type overvoltages from switching or lightning transients per IEC 61000-4-5, and recommends external protection along with cable-length limits (power cable <= 3 m, data line <= 30 m) if that standard applies. This should be verified against the actual system wiring topology and any co-located switching converters, since inductive sensors of this type are sensitive to loop layout and EMI coupling in motor-adjacent installations. The stated ESD rating (2 kV contact discharge, connector interface only, per EN 61000-4-2:2008 Level 1) is a component-level stress test result and does not by itself establish system-level EMC compliance; this does not replace system-level validation. Mechanical mounting tolerances are explicit in the datasheet: rotor shaft diameter Ø5 g6, stator centering diameter Ø45 H7, air-gap 0.4 mm +/- 0.15 mm, and total beat/runout limits under 0.2 mm. In a typical off-axis hollow-shaft installation, meeting these mechanical tolerances is necessary to achieve the specified accuracy and repeatability figures; the manufacturer recommends a cone centering tool during assembly to help meet these limits. Application fit. Applications such as hospital beds, surgical tables, drones, and missile launchers are listed by the manufacturer as market applications, but the source provides no application-specific qualification data (e.g., medical or aerospace certification) beyond the general industrial ratings; engineers in regulated markets should confirm whether additional qualification is required. Verification checklist. * Confirm absolute accuracy budget by combining the 25°C figure (>= 10 bits, 0.35°) with the +/- 0.16° temperature derating across the intended operating range. * Verify whether the 125°C or 105°C upper temperature limit applies, since the datasheet differentiates pads-variant and connector-variant maximum temperatures. * Check SPI timing margins (clock frequency 100 kHz-1.4 MHz, inactive time >= 500 ns, processing time >= 400 ns) against the host controller's SPI interface configuration. * Assess whether external surge protection (IEC 61000-4-5) is needed, and confirm power/data cable length limits (3 m / 30 m) against the installation's actual wiring. * Validate mechanical mounting tolerances (rotor Ø5 g6, stator Ø45 H7, air-gap 0.4 mm +/- 0.15 mm, beat < 0.2 mm) using the recommended cone centering tool or the alternative external-diameter centering method. * Confirm environmental protection needs (conformal coating or potting) if the application involves metallic particles, oils, greases, salt spray, or corrosion, since these are offered only on request. * Verify current sample/production availability and the stated 16-week lead time directly with Vishay or an authorized distributor before committing to a design timeline. Availability and configuration status. The press release states that samples and production quantities of the RAIK045I MP are available now, with lead times of 16 weeks. Options such as pad connection, analog output, and Sin/Cos output are noted in the datasheet as available "on request," indicating these are not standard off-the-shelf configurations. Engineers should confirm current part-specific ordering status and configuration options through Vishay's product finder or an authorized distributor before design release. This article is based on Vishay Intertechnology's official press release for the RAIK045I MP and the associated manufacturer datasheet (document number 32647). Engineers should consult the current Vishay datasheet, mounting drawings, and application information directly from Vishay for final component selection, validation, and design release.
