AS3BGHM3_A/H

Overview

The AS3BGHM3_A/H is a single standard recovery rectifier manufactured by Vishay Semiconductors. It features a 400 V repetitive peak reverse voltage and a 3 A average forward current rating. The device utilizes an eSMP technology with an avalanche capability, housed in a DO-214AA (SMB) surface-mount package. Key electrical parameters include a maximum forward voltage of 980 mV at 3 A, a surge current capacity of 90 A, and a reverse leakage current of 500 nA. It operates within a junction temperature range of -55 °C to +175 °C and holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Features avalanche-rated capability for robust operation under transient conditions
• Utilizes eSMP technology for high reliability and low thermal resistance
• Housed in a compact DO-214AA (SMB) surface-mount package for automated assembly

Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• General-purpose rectification in industrial power supplies
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix _A/H against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure that the AEC-Q101 qualification status aligns with your project's automotive reliability requirements. Cross-reference the DO-214AA footprint dimensions with your PCB design guidelines to guarantee mechanical compatibility during surface-mount placement.

Selection Notes

Select this component when a standard recovery rectifier with avalanche capability is required in an SMB package. The 400 V rating suits medium-voltage DC applications, while the 3 A current handling supports moderate power levels. Consider the 980 mV forward voltage drop for efficiency calculations in low-to-medium voltage conversion circuits where standard recovery characteristics are acceptable.

Part Context

This part belongs to Vishay's eSMP series of surface-mount rectifiers. The AS3B prefix indicates a 3 A standard recovery diode with a 400 V voltage rating. The HM3 suffix denotes halogen-free construction compliant with RoHS directives. The _A/H suffix typically specifies the specific packaging configuration, such as cut tape or reel options, rather than altering the electrical function.
