SEMICONDUCTOR TECHNICAL DATA
Silicon Controlled Rectifiers
Reverse Blocking Triode Thyristors
. . . designed primarily for full-wave ac control applications, such as motor controls,
heating controls and power supplies; or wherever half-wave silicon gate-controlled,
solid-state devices are needed.
• Glass Passivated Junctions and Center Gate Fire for Greater Parameter
Uniformity and Stability
• Small, Rugged, Thermowatt Construction for Low Thermal Resistance, High Heat
Dissipation and Durability
• Blocking Voltage to 800 Volts
• Different Leadform Configurations,
Suffix (2) thru (6) available, see Leadform Options (Section 4) for Information

1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, (cont.)
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.
