VI40120C-M3/4W

Diode Arrays Overview

The VI40120C-M3/4W is a dual high voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a common cathode configuration with two diodes housed in a TO-262AA package. The device supports a maximum repetitive peak reverse voltage of 120 V and an average forward rectified current of 40 A per device (20 A per diode). Key electrical parameters include a peak forward surge current of 250 A, a typical thermal resistance of 1.8 °C/W per diode, and a maximum operating junction temperature of 150 °C.

Diode Arrays Feature Summary

• Utilizes Trench MOS Schottky technology to achieve low forward voltage drop and reduced power losses.

Diode Arrays Procurement Notes

Verify the specific ordering suffix /4W corresponds to the tube packaging format containing 50 units per tube as defined in the manufacturer's ordering information. Confirm that the M3 suffix indicates compliance with RoHS directives and halogen-free requirements. Ensure the component meets the material categorization definitions provided in the Vishay documentation before finalizing procurement specifications.

Diode Arrays Selection Notes

Select this component when a dual common cathode Schottky rectifier is required for applications demanding low forward voltage at high currents. The TO-262AA package provides suitable mounting options for through-hole assembly. Consider the 150 °C maximum junction temperature rating for thermal management in high-power environments. Validate that the 120 V reverse voltage rating aligns with the system's peak reverse voltage requirements.

Diode Arrays Part Context

This part belongs to the V40120C series of dual high voltage TMBS rectifiers from Vishay. The VI40120C designation specifically identifies the version packaged in the TO-262AA case style, distinguishing it from the TO-220AB variant. Both variants share identical electrical characteristics and performance metrics while differing only in physical package dimensions.

Diode Arrays Replacement Considerations

V40120C-M3/4W serves as the direct pin-compatible replacement within the same product family, utilizing the TO-220AB package instead of TO-262AA.
