16 Amp High Junction Temperature SCRs
RoHS
SJxx16xx Series
Description
This SJxx16xx high junction 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 offer low gate current trigger levels of 6 mA,
10 mA, or 30 mA at approximately 1.5V.
Features & Benefits
• Halogen free and RoHS
compliant
• Surge capability up to
225A at 60 Hz half cycle
• 150°C maximum junction
temperature
• Recognized to UL 1557
as an Electrically Isolated
Semiconductor Device
