AS3BGHM3_A/I

Overview

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

Feature Summary

• Avalanche rated capability for robust operation in inductive switching environments
• AEC-Q101 qualified for automotive electronics reliability standards
• Utilizes eSMP technology for enhanced performance characteristics

Applications

• Automotive power supply circuits
• General-purpose rectification in industrial equipment
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix configuration against official Vishay documentation to ensure correct packaging and qualification status. Confirm that the DO-214AA footprint matches the target PCB design. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing component selection for production.

Selection Notes

Select this component when a single-phase rectifier with avalanche ruggedness is required for automotive or high-reliability industrial applications. The SMB package offers a compact solution for space-constrained designs. Ensure the circuit's reverse voltage stress remains below the 400 V rating and that thermal management accommodates the specified operating temperature range.

Part Context

This part belongs to the AS3B series of standard recovery rectifiers from Vishay. The series provides solutions for general-purpose rectification in various power conversion topologies. The HM3 designation indicates lead-free construction compliant with RoHS directives, while the AEC-Q101 qualification distinguishes it for automotive-grade deployment requirements.

Replacement Considerations

Direct substitutes include other Vishay AS3B series variants such as AS3BG-M3/I for non-automotive contexts. Verify pinout compatibility and thermal resistance specifications when considering cross-brand alternatives to ensure equivalent performance in the target application.
