AR1PGHM3/84A

Overview

The AR1PGHM3/84A is a single ultrafast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 400 V maximum repetitive reverse voltage and supports an average forward rectified current of 1 A. The device utilizes the eSMP package (DO-220AA) for surface mount installation. Key electrical parameters include a maximum forward voltage of 1.25 V at 1 A, a reverse leakage current of 2 µA at 400 V, and a typical reverse recovery time of 75 ns. It operates within a junction temperature range of -55°C to +175°C and holds AEC-Q101 qualification.

Feature Summary

• Ultrafast recovery characteristics with low reverse recovery charge
• High thermal stability supporting high junction temperatures up to 175°C
• Automotive grade reliability certified under AEC-Q101 standards
• Compact surface-mount packaging for automated assembly

Applications

• Automotive power supply circuits
• DC-DC converter freewheeling diodes
• High-frequency switching applications
• Industrial motor drive protection

Procurement Notes

Verify the specific suffix /84A corresponds to the Tape & Reel packaging configuration when ordering. Confirm that the AEC-Q101 qualification meets your automotive project requirements. Ensure the DO-220AA footprint matches your PCB design guidelines. Cross-reference the datasheet for exact thermal resistance values if heatsinking is required.

Selection Notes

Select this component for applications requiring fast switching speeds and high voltage blocking capabilities in a compact form factor. The 400 V rating provides sufficient margin for standard 24 V or 48 V systems. Consider the 1 A current limit for load requirements. The ultrafast recovery minimizes switching losses compared to standard rectifiers.

Part Context

This part belongs to Vishay's eSMP series of surface mount rectifiers. It is designed to replace through-hole equivalents in modern compact electronics. The AR1P series focuses on high-speed performance suitable for demanding power conversion environments. It complements other Vishay diode families offering similar voltage and current ratings.

Replacement Considerations

Check for direct substitutes such as AR1PG-M3/84A or AR1PGHM3/85A which share similar electrical profiles. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same AEC-Q101 automotive qualification if applicable.
