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 supplies; or wherever half–wave, silicon
gate–controlled devices are needed.
• Blocking Voltage to 800 Volts
• On-State Current Rating of 25 Amperes RMS
• High Surge Current Capability — 300 Amperes
• Industry Standard TO–220AB Package for Ease of Design
• Glass Passivated Junctions for Reliability and Uniformity

(1) VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; 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.
Preferred devices are Motorola recommended choices for future use and best overall value.
