AS3BJHM3_A/H

Overview

The AS3BJHM3_A/H is a standard avalanche surface-mount rectifier manufactured by Vishay General Semiconductor. It features a glass passivated chip junction and is housed in an SMB (DO-214AA) package. The device supports a maximum repetitive peak reverse voltage of 600 V and a DC forward current of 3.0 A. It exhibits a typical instantaneous forward voltage of 0.98 V at 3.0 A and 25 °C, with a non-repetitive avalanche energy rating of 20 mJ. The component operates within a temperature range of -55 to +175 °C and is qualified under the AEC-Q101 automotive standard.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Controlled avalanche characteristics for robust performance
• Low profile package suitable for automated placement
• AEC-Q101 qualification for automotive applications

Applications

• General purpose rectification in power supplies
• Freewheeling diodes for consumer electronics
• Inverter and converter circuits
• Telecommunication equipment

Procurement Notes

Verify that the ordering code includes the HM3 suffix to confirm AEC-Q101 qualification and halogen-free compliance. Ensure the base quantity matches the required delivery mode, such as 750 units for the 7-inch tape and reel or 3200 units for the 13-inch tape and reel. Confirm the revision code corresponds to the specific manufacturing batch requirements.

Selection Notes

Select this component when a 600 V reverse voltage rating and 3.0 A continuous forward current are required in an SMB package. Consider its controlled avalanche capability if the circuit design involves potential inductive load switching. Verify thermal management needs against the specified junction-to-ambient thermal resistance for the intended operating environment.

Part Context

This part belongs to the AS3BD, AS3BG, and AS3BJ series of standard avalanche surface-mount rectifiers from Vishay. These devices share identical mechanical dimensions and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings. The AS3BJ variant specifically provides the highest voltage rating within this low-profile family.

Replacement Considerations

Direct substitutes include AS3BGHM3_A/H for lower voltage applications and AS3BDHM3_A/H for even lower voltage requirements. Cross-reference with other SMB packaged 600 V, 3 A standard recovery rectifiers only if avalanche characteristics are not critical to the application design.
