TRIACS

Silicon Bidirectional Thyristors

Designed for industrial and consumer applications for full wave control of ac

loads such as appliance controls, heater controls, motor controls, and other

power switching applications.

• Sensitive Gate Allows Triggering by Microcontrollers and other Logic

Circuits

• High Immunity to dv/dt — 25 V/ms Minimum at 110_C

• High Commutating di/dt — 8.0 A/ms Minimum at 110_C

• Minimum and Maximum Values of IGT, VGT and IH Specified for ease of

Design

• On-State Current Rating of 8 Amperes RMS at 70_C

• High Surge Current Capability — 70 Amperes

• Blocking Voltage to 800 Volts

• Rugged, Economical TO220AB Package
