VI30120SG-M3/4W

Single Diodes Overview

The VI30120SG-M3/4W is a high-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a TO-262AA surface-mount package and provides a maximum repetitive peak reverse voltage of 120 V with an average forward rectified current rating of 30 A. The device exhibits an ultra-low forward voltage drop, specified as 0.47 V at 5 A and 0.81 V at 30 A under elevated temperature conditions. It supports a peak forward surge current of 220 A and operates within a junction temperature range of -40 °C to +150 °C.

Single Diodes Feature Summary

• Utilizes Trench MOS Schottky technology to achieve low forward voltage drop and reduced power losses.
• Designed for high efficiency operation in switching applications.
• Halogen-free construction compliant with RoHS directives.

Single Diodes Applications

• High frequency DC/DC converters
• Switching power supplies
• Freewheeling diodes
• OR-ing diode circuits
• Reverse battery protection

Single Diodes Procurement Notes

Verify the specific suffix 'M3' confirms halogen-free status and compliance with JESD 201 class 1A whisker testing requirements. Ensure the ordering code matches the TO-262AA package variant rather than the through-hole TO-220AB version. Confirm that the base quantity aligns with standard tube packaging specifications provided by the manufacturer.

Single Diodes Selection Notes

Select this component when low conduction loss is critical for thermal management in high-current applications. The TMBS architecture offers superior performance compared to standard silicon rectifiers. Verify that the 120 V reverse voltage rating accommodates system transients and that the 30 A continuous current capability meets the load requirements without excessive derating.

Single Diodes Part Context

This part belongs to the V30120SG series of high-voltage Trench MOS Barrier Schottky Rectifiers. The SG designation indicates the specific electrical characteristics optimized for low forward voltage. The M3 suffix denotes environmental compliance including halogen-free materials and lead-free terminals. The 4W package code corresponds to the TO-262AA form factor.

Single Diodes Replacement Considerations

Direct substitutes include the V30120SG-M3/4W which shares identical electrical ratings but utilizes a TO-220AB through-hole package. Cross-reference pinout configurations carefully when transitioning between surface-mount and through-hole variants to ensure correct circuit integration.

Single Diodes FAQ

What is the typical thermal resistance from junction to case?

The typical thermal resistance (RθJC) is 1.6 °C/W.

Does the M3 suffix affect the electrical performance of the diode?

No, the M3 suffix indicates material compliance such as being halogen-free and meeting whisker test standards, but does not alter the electrical parameters.
