AS4PGHM3_A/I

Overview

The AS4PGHM3_A/I is a single standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 4 A per diode. The device utilizes the SMPC (TO-277A-3) surface-mount package. Key electrical parameters include a maximum forward voltage (Vf) of 920 mV at 4 A, a peak repetitive reverse voltage of 400 V, and a maximum non-repetitive peak forward surge current of 100 A. The junction temperature range extends from -55°C to +175°C, and it holds AEC-Q101 qualification for automotive applications.
