AS4PM-M3/87A

Overview

The AS4PM-M3/87A is a standard recovery rectifier from Vishay, housed in the SMPC (TO-277A-3) surface-mount package. It features a 1000 V reverse voltage rating and supports a continuous forward current of 4 A. The device exhibits a maximum forward voltage of 1.044 V and a reverse leakage current of 350 nA. Its peak surge current capacity is 100 A, with a reverse recovery time of 1.8 µs. Operating temperatures range from -55 °C to +175 °C.

Feature Summary

• Glass passivated for environmental durability
• High thermal performance enabling operation up to 175 °C junction temperature
• Designed for high-reliability applications requiring robust surge handling

Applications

• General-purpose rectification in power supplies
• Protection circuits requiring avalanche capability
• Industrial equipment power stages

Procurement Notes

Verify the specific suffix /87A against official datasheets to confirm reel packaging specifications. Ensure compatibility with SMPC footprint requirements during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when high reverse voltage blocking and moderate speed are required in a compact surface-mount form factor. The dual-anode configuration offers flexibility in circuit design. Consider the 175 °C operating limit for high-temperature environments compared to standard 150 °C alternatives.

Part Context

This part belongs to the AS4P series of glass-passivated silicon rectifiers. It utilizes the eSMP trademarked SMPC package, which provides improved thermal dissipation compared to traditional DO-201AD packages while maintaining similar electrical characteristics for space-constrained designs.

Replacement Considerations

Check AS4PM-M3/86A for cut-tape availability or different reel quantities. Verify equivalent parts from other manufacturers offering TO-277A-3 packages with matching 1000 V and 4 A ratings.
