SJxx25xxA Series
25 Amps High Junction Temperature SCRs
RoHS
Description
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.
