SEMICONDUCTOR TECHNICAL DATA
Silicon Controlled Rectifiers
Reverse Blocking Thyristors
. . . designed primarily for half-wave ac control applications, such as motor controls,
heating controls and power supply crowbar circuits.
• Glass Passivated Junctions with Center Gate Fire for Greater Parameter Uniformity
and Stability
• Small, Rugged, Thermowatt Constructed for Low Thermal Resistance, High Heat
Dissipation and Durability
• Blocking Voltage to 800 Volts
• 300 A Surge Current Capability
• Insulated Package Simplifies Mounting

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.
2. The case temperature reference point for all TC measurements is a point on the center lead of the package as close as possible to the plastic
body.
