Product data sheet
1. General description
Planar passivated four quadrant triac in a SOT78 (TO-220AB) plastic package intended
for use in applications requiring high bidirectional transient and blocking voltage
capability and high thermal cycling performance. Typical applications include motor
control, industrial and domestic lighting, heating and static switching.
2. Features and benefits
