AU1PM-M3/84A

Overview

The AU1PM-M3/84A is a single ultrafast recovery rectifier manufactured by Vishay Semiconductors. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 1 kV. The device utilizes the eSMP package (DO-220AA) for surface mount installation. Key electrical parameters include a maximum forward voltage of 1.85 V, a reverse leakage current of 1 uA, and a maximum surge current of 25 A. The component operates within a junction temperature range of -55 C to +175 C and exhibits a typical reverse recovery time of 75 ns.

Feature Summary

• Ultrafast recovery characteristics designed for high-speed switching applications
• High thermal stability supporting operation up to 175 C junction temperature
• Low reverse leakage current ensuring efficient performance in high-voltage environments

Applications

• High-frequency power supply circuits
• Free-wheeling diodes in DC-DC converters
• Snubber circuits in industrial electronics

Procurement Notes

Verify the specific suffix /84A corresponds to the required tape and reel packaging configuration before ordering. Confirm RoHS compliance status via the official datasheet as regulatory requirements may vary by region. Ensure the DO-220AA footprint matches the target PCB design constraints. Cross-reference the manufacturer part number with authorized distributors to prevent counterfeit components.

Selection Notes

Select this component when a 1 kV blocking capability is required alongside fast recovery times. The 1 A current rating suits moderate power applications where space efficiency is critical. Consider the 1.85 V forward voltage drop for thermal management calculations. Compare against lower voltage variants if system requirements allow for reduced stress on the semiconductor junction.
