Silicon Controlled Rectifiers
Reverse Blocking Triode Thyristors
. . . designed for industrial and consumer applications such as temperature, light and
speed control; process and remote controls; warning systems; capacitive discharge
circuits and MPU interface.
• Center Gate Geometry for Uniform Current Density
• All Diffused and Glass-Passivated Junctions for Parameter Uniformity and
Stability
• Small, Rugged Thermowatt Construction for Low Thermal Resistance, High Heat
Dissipation and Durability
• Low Trigger Currents, 200 µA Maximum for Direct Driving from Integrated Circuits

1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage;
however, positive gate voltage shall not be applied concurrent with negative potential on the anode. Blocking voltages
shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded.
