Silicon Controlled Rectifier
Reverse Blocking Triode Thyristor
... 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 jiA Maximum for Direct Driving from Integrated
