1N4587R

Overview

The 1N4587R is a standard silicon rectifier diode manufactured by Microchip Technology. It features a maximum DC reverse voltage of 100 V and an average forward current rating of 150 A. The device utilizes a DO-205AA (DO-8) screw-type package with an anode case connection. It operates as a single-element, standard recovery diode with a reverse recovery time exceeding 500 ns. Key electrical parameters include a maximum reverse leakage current of 50 uA and a forward voltage drop of 1.1 V.

Feature Summary

• Standard recovery speed for general-purpose power applications
• High current handling capability up to 150 A
• Robust screw-terminal mounting for secure connections

Applications

• Power supply circuits
• General purpose rectification
• Soft recovery power applications

Procurement Notes

Verify the manufacturer designation carefully, as Powerex Inc. also produces this part number. Confirm the specific datasheet version matches your design requirements. Ensure the DO-205AA package dimensions align with your thermal and mechanical constraints. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component for high-current, low-voltage rectification tasks requiring standard recovery characteristics. The 100 V reverse voltage rating suits low-side AC-to-DC conversion. Consider the 1.1 V forward voltage drop for efficiency calculations. The screw-mount style necessitates appropriate heatsinking infrastructure in the final assembly.

Part Context

This part belongs to the 1N4587 series of standard rectifiers. It shares characteristics with other 1N4xxx series devices but is distinguished by its specific 150 A current rating and 100 V blocking voltage. It serves as a robust solution for industrial power electronics where reliability under high load conditions is critical.

Replacement Considerations

Cross-reference with 1N4587 from various manufacturers. Verify pinout compatibility and thermal resistance values before substitution.
