SEMICONDUCTOR TECHNICAL DATA

Triacs

Silicon Bidirectional Thyristors

. . . designed primarily for full-wave ac control applications, such as light dimmers,
motor controls, heating controls and power supplies.

• Blocking Voltage to 600 Volts

• Glass Passivated Junctions for Greater Parameter Uniformity and Stability

• TO-220 Construction Low Thermal Resistance, High Heat Dissipation and Dura-

bility

• Gate Triggering Guaranteed in Four Modes
