Description

General part information

SJ4020 Series

This SJxx25xxA high temperature SCR series is ideal for uni-directional switch applications such as phase control in heating, motor speed controls, converters/rectifiers and inrush current controllers. These SCRs have a low gate current trigger level of 6mA,10mA or 35mA maximum at approximately 1.5V
