1N4003GPHM3/54

Single Diodes Overview

The Vishay 1N4003GPHM3/54 is a general-purpose plastic rectifier diode belonging to the 1N400x series. It features a maximum repetitive peak reverse voltage of 200 V and supports a maximum average forward rectified current of 1.0 A at 75 °C. The device utilizes a DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 1.0 A, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a typical junction capacitance of 15 pF at 4.0 V and 1 MHz. Peak non-repetitive forward surge current reaches 30 A for an 8.3 ms sine wave or 45 A for a 1 ms square wave.
