1N4002B-G

Single Diodes Overview

The Comchip Technology 1N4002B-G is a general-purpose silicon rectifier diode designed for through-hole mounting in the DO-41 package. It features a maximum average forward rectified current of 1 A and a peak repetitive reverse voltage of 100 V. The device exhibits a low forward voltage drop and high surge current capability, with a non-repetitive peak forward surge current rating of 30 A. It operates within a junction temperature range of -65°C to +175°C and includes glass passivation for mechanical strength.
