VB40100C-M3/4W

Diode Arrays Overview

The VB40100C-M3/4W is a dual high-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a common cathode configuration in a D2PAK (TO-263AB) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 100 V and a total maximum average forward rectified current of 40 A, with 20 A per diode. The device supports a peak forward surge current of 250 A and operates within a junction temperature range of -40 °C to +150 °C. Forward voltage drop is specified at 0.73 V maximum at 20 A and 25 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix /4W corresponds to the tube packaging format containing 50 units per tube. Confirm that the M3 suffix indicates compliance with halogen-free standards and RoHS directives as defined by the manufacturer. Ensure the component meets JESD 201 class 2 whisker test requirements before final integration into the design.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage drop to minimize conduction losses. The D2PAK package offers a balance of current handling capability and thermal performance suitable for surface mount designs. Verify that the 100 V reverse voltage rating provides adequate margin for the specific circuit operating conditions.

Diode Arrays Part Context

This part belongs to the VB40100C series of dual high-voltage TMBS rectifiers. The M3 suffix denotes environmental compliance including halogen-free materials and RoHS adherence. The /4W suffix specifically identifies the tube packaging option, distinguishing it from tape and reel variants like the /8W.

Diode Arrays Replacement Considerations

Direct replacements must match the 100 V reverse voltage, 20 A per diode current rating, and TO-263AB package outline. Verify thermal resistance characteristics and forward voltage specifications to ensure equivalent performance in the target application.
