Preferred Device
Triacs
Silicon Bidirectional Thyristors
Designed primarily for full-wave ac control applications, such as
light dimmers, motor controls, heating controls and power supplies; or
wherever fullwave silicon gate controlled solidstate devices are
needed. Triac type thyristors switch from a blocking to a conducting
state for either polarity of applied main terminal voltage with positive
or negative gate triggering.
Features
Blocking Voltage to 800 V
All Diffused and Glass Passivated Junctions for Greater Parameter
Uniformity and Stability
Small, Rugged, Thermowatt Construction for Low Thermal
Resistance, High Heat Dissipation and Durability
Gate Triggering Guaranteed in all Four Quadrants
For 400 Hz Operation, Consult Factory
PbFree Package is Available*

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
