AS4PK-M3/87A

Overview

The AS4PK-M3/87A is an Avalanche-rated single diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 800 V and an average forward rectifier current (Io) of 2.4 A. The component utilizes the eSMP package, identified as TO-277A-3, for surface mount installation. It operates within a junction temperature range of -55°C to +150°C. This device belongs to the AS3P series and is designed for robust performance in high-voltage applications requiring avalanche capability.

Feature Summary

Avalanche rated construction for enhanced ruggedness
High voltage blocking capability up to 800 V
Surface mount eSMP (TO-277A-3) packaging

Applications

Automotive electronics
Industrial power supplies
General purpose rectification

Procurement Notes

Verify the specific suffix /87A corresponds to the reel packaging configuration required for your assembly line. Confirm RoHS compliance status through the official datasheet before integration. Ensure the TO-277A-3 footprint matches your PCB design guidelines. Cross-reference the manufacturer's latest documentation for any potential lifecycle changes or alternative recommendations.

Selection Notes

Select this component when an 800 V reverse voltage rating and 2.4 A continuous current are required in a compact surface mount form factor. The avalanche rating makes it suitable for environments with potential inductive load switching or voltage transients. Consider the thermal characteristics of the TO-277A-3 package for heat dissipation requirements in your specific circuit layout.

Part Context

This part belongs to the AS3P series of avalanche rectifiers from Vishay. These devices are engineered for automotive and industrial applications where reliability under stress conditions is critical. The eSMP package provides a small outline solution that facilitates automated placement while maintaining electrical performance comparable to larger through-hole alternatives.
