1N2129A

Single Diodes Overview

The Microchip Technology 1N2129A is a standard recovery power silicon rectifier diode designed for high-current applications. It features a maximum average forward rectified current of 60 A at a case temperature of 140°C and a maximum repetitive peak reverse voltage of 100 V. The device utilizes a stud mount configuration with a 1/4"-28 UNF-2A thread, housed in a DO-5 (DO-203AB) package. Key electrical characteristics include a maximum forward voltage drop of 1.1 V and a maximum non-repetitive surge current capability of 1.05 kA.
