Vishay Electronic Components and Semiconductors

Siliconix power MOSFET architecture and silicon carbide switching devices

Vishay Siliconix power MOSFET devices lead industrial automation power electronics through persistent refinements in silicon die geometries and packaging.

Fourth and fifth generation TrenchFET architectures achieve ultra-low on-state channel resistance under elevated operating temperatures, essential for industrial switching power supplies, servo converters and CNC spindle drives.

In higher voltage tiers, Superjunction E and EF devices feature optimized gate charge metrics to reduce dynamic switching losses during high-frequency operation.

For industrial designs requiring exceptional power density, MaxSiC silicon carbide switching transistors deliver 1200 V blocking capability with minimal recovery stress.

Packaged in low-inductance PowerPAK SO-8, 1212-8 and 8x8 outlines with exposed thermal pads, these parts ensure robust heat removal within compact multi-layer PCB layouts.

FRED Pt rectifiers, TMBS Schottky diodes and TRANSZORB protection

Vishay Semiconductor rectifiers combine rapid commutation with low forward conduction losses. Patented Trench MOS Barrier Schottky (TMBS) technology overcomes planar Schottky trade-offs, enabling operation up to 200 V with reduced forward drop and stable leakage current across thermal cycles.

This architecture provides reliable secondary rectification across industrial switch-mode equipment.

High-voltage inverter sections employ ultrafast FRED Pt rectifiers with platinum-doped junctions that guarantee soft recovery behavior without destructive ringing.

To protect sensitive controller logic from voltage transients and inductive spikes, planar eSMP outlines house TRANSZORB and Paravolt transient voltage suppressors.

Power Metal Strip shunts and precision resistors from Vishay brands

Vishay resistive components integrate renowned brands including Dale, Beyschlag, Draloric and Sfernice. A defining technology is the Power Metal Strip current sense resistor line across WSL, WSLP and WSKW series, built with a solid metal alloy resistive element.

This all-welded construction yields long-term stability, minimal parasitic inductance and temperature coefficients down to 15 ppm/°C under cycling load conditions.

Precision sensor front-ends rely on Beyschlag thin-film surface mount resistors featuring tight 0.01% tolerance and negligible long-term drift under continuous loading.

High-power wirewound and thick-film Dale and Draloric resistors housed in aluminum heatsink profiles support dynamic motor braking and inrush limiting.

Tantalum, suppression film, MLCC ceramic and heavy power capacitors

Vishay capacitance solutions span comprehensive dielectric technologies tailored for industrial equipment. Tantalum polymer capacitors from Sprague and vPolyTan provide extremely low equivalent series resistance (ESR) and high ripple current ratings.

Hermetically sealed TANTAMOUNT devices ensure uninterrupted operation under severe environmental moisture and mechanical vibration.

For AC line electromagnetic suppression, Roederstein polypropylene and polyester film capacitors meet X1, X2 and Y2 safety standards.

Industrial power factor correction and harmonic mitigation panels employ Vishay ESTA dry power capacitors, while ENYCAP double-layer supercapacitors deliver backup energy storage.

Integrated microBUCK regulators and VRPower DrMOS power modules

To power low-voltage microcontrollers, FPGAs, DSPs and interface buses on industrial logic boards, Vishay produces integrated power conversion circuits.

The microBUCK family integrates a PWM controller and TrenchFET switches into a miniature footprint, delivering efficiency up to 95% from input voltages up to 60 V with continuous load currents up to 40 A across automation equipment.

VRPower DrMOS smart power stages combine an optimized gate driver and high-side/low-side MOSFETs within a compact multi-chip footprint to eliminate stray interconnect inductance.

In the microBRICK series, a shielded magnetic inductor is co-packaged internally to cut motherboard footprint requirements.

Component identification and bill of materials matching for Vishay hardware

Our engineering specialists support industrial facilities with component verification and matching using machine serial plates, circuit schematics, bill of materials or factory part numbers.

When legacy components face end-of-life discontinuations, we calculate and coordinate functional replacements with enhanced reliability, temperature tolerance and thermal dissipation.

Electronic components arrive in standard manufacturer packaging including tape-and-reel, tubes and ESD protective trays complying with strict handling requirements. Shipments include comprehensive technical datasheets, inspection packing slips and full commercial compliance documentation.
