AR4PDHM3/87A

Single Diodes Overview

The AR4PDHM3/87A is a silicon rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 600 V and an average forward rectified current (Io) of 2 A. The device utilizes the TO-277A (SMPC) surface-mount package with three terminals. Key electrical characteristics include a maximum forward voltage (Vf) of 1.6 V at 4 A, a maximum non-repetitive peak forward surge current of 80 A, and a reverse leakage current of 10 µA at 600 V. The junction temperature range spans from -55 °C to +175 °C.

Single Diodes Procurement Notes

Verify the specific suffix '87A' against official Vishay documentation to confirm reel packaging specifications. Ensure the component meets RoHS3 compliance requirements for your manufacturing process. Cross-reference the datasheet revision date to validate technical parameters before integration into final designs.

Single Diodes Selection Notes

Select this component when a 600 V reverse voltage rating and 2 A continuous current capacity are required in a small surface-mount footprint. Consider the 175 °C maximum junction temperature for high-thermal environments. Evaluate the 1.6 V forward voltage drop for efficiency calculations in low-voltage DC circuits.
