Motorola Thyristor Device Data

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.
