AU1PGHM3/84A

Overview

The AU1PGHM3/84A is a single ultrafast recovery rectifier manufactured by Vishay Semiconductors. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 400 V. The device utilizes the eSMP package, specifically DO-220AA, for surface-mount installation. Key electrical characteristics include a maximum forward voltage of 1.5 V at rated current and a typical reverse leakage current of 1 µA. The unit supports a maximum surge current of 25 A and operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Ultrafast recovery technology designed for high-speed switching applications
• Plastic material qualified per UL 94 V-0 flammability rating standards
• Low thermal resistance enabling efficient heat dissipation in compact designs

Applications

• High-frequency power supply circuits
• Free-wheeling diode implementations in inductive loads
• DC-DC converter output rectification stages

Procurement Notes

Verify the specific suffix /84A against official datasheets to confirm reel packaging specifications. Ensure compatibility with automated pick-and-place equipment due to the SMD form factor. Cross-reference RoHS compliance status with the latest manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when circuit requirements demand fast recovery times combined with moderate voltage blocking capabilities. The 1 A current rating suits low-to-medium power conversion tasks. Evaluate thermal management needs based on the specified operating temperature limits and package constraints.

Part Context

This part belongs to Vishay's eSMP series of surface-mount rectifiers. It shares the DO-220AA footprint with other variants in the lineup but differs in voltage and speed ratings. The designation indicates a lead-free finish compliant with international environmental directives.

Replacement Considerations

Consult official substitution guides for equivalent ultrafast rectifiers with matching 400 V and 1 A ratings. Verify pinout compatibility and thermal performance metrics before integrating alternative components into existing layouts.
