40 Amp Standard SCRs

Sxx40x Series

SJxx40xx Series

Description

This SJxx40xx high temperature SCR series is ideal for

uni-directional switch applications such as phase control in

heating, motor speed controls and AC rectifier and voltage

regulator.

These SCRs have a low gate current trigger level of 40 mA

maximum at approximately 1.5 V, with a sensitive version of

this series having a gate trigger current of 15 mA maximum.

Features & Benefits

• High junction temperature

• Voltage capability up

to 600 V

• Surge capability up to

520 A at 60 Hz half cycle

• Halogen free and RoHS

compliant
