VB20100S-M3/8W

Single Diodes Overview

The VB20100S-M3/8W is a high voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a D2PAK (TO-263AB) surface-mount package and supports a maximum repetitive peak reverse voltage of 100 V with an average forward rectified current rating of 20 A. The device exhibits ultra-low forward voltage characteristics, reaching 0.446 V at 5 A and 0.69 V at 20 A. It offers a peak forward surge current capability of 250 A and operates within a junction temperature range of -40 to +150 °C.

Single Diodes Feature Summary

• Utilizes Trench MOS Schottky technology for low forward voltage drop and reduced power losses
• Provides high efficiency operation through optimized barrier structure
• Features low thermal resistance for effective heat dissipation in surface-mount applications

Single Diodes Applications

• High frequency converters
• Switching power supplies
• Freewheeling diodes
• DC/DC converters
• Reverse battery protection circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm the required delivery mode and packaging quantity. The /8W suffix indicates tape and reel packaging with a base quantity of 800 units per reel. Confirm that the component meets halogen-free and RoHS compliance requirements as specified in the mechanical data section before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a surface-mount Schottky rectifier with low forward voltage is required for high-frequency switching applications. Ensure the design accommodates the 100 V reverse voltage rating and 20 A continuous current capability. Consider the thermal management requirements based on the junction-to-case thermal resistance provided in the datasheet for the D2PAK package.

Single Diodes Part Context

This part belongs to the VF20100S/VB20100S series of High Voltage TMBS rectifiers from Vishay. The series includes variants with different packages such as ITO-220AB and D2PAK (TO-263AB). The VB20100S-M3/8W specifically denotes the D2PAK package variant supplied in tape and reel format, distinguishing it from tube-packaged versions like the VF20100S-M3/4W.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay TMBS rectifiers in the same voltage and current class, such as the VF20100S-M3/4W for tube packaging or the VI20100S-M3 for leaded packages. Verify pinout compatibility and thermal resistance differences when replacing with non-Vishay equivalents.
