VF20150S-M3/4W

Single Diodes Overview

The VF20150S-M3/4W is a high-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features an ITO-220AB case and provides a maximum repetitive peak reverse voltage of 150 V with a maximum average forward rectified current of 20 A. The device exhibits ultra-low forward voltage characteristics, reaching 0.55 V at 5 A and 0.75 V at 20 A. It supports a peak forward surge current of 160 A and operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific ordering code VF20150S-M3/4W against official Vishay documentation to confirm compliance with RoHS directives and halogen-free requirements. Ensure the package code 4W matches the required tube quantity and delivery mode. Confirm thermal resistance ratings and mounting torque specifications align with the target heatsink design before finalizing procurement.

Single Diodes Selection Notes

Select this component when designing circuits requiring a single Schottky rectifier with a 150 V blocking capability and 20 A continuous current handling. The TMBS technology offers superior performance compared to standard silicon rectifiers. Consider the 4.0 °C/W thermal resistance for adequate heat dissipation planning in high ambient temperature environments.

Single Diodes Part Context

This part belongs to the VF series of high-voltage Trench MOS Barrier Schottky Rectifiers from Vishay. It is designed as a direct replacement for legacy components in power supply designs where lower forward voltage drop is critical for improving overall system efficiency and reducing thermal management complexity.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay TMBS devices such as the VF20100S or VF30150S, provided the voltage and current ratings meet the circuit requirements. Verify pinout compatibility and thermal characteristics when transitioning between different packages or current ratings.
