TLC336A 600V 3A TRIAC TO-202

TLC336A 600V 3A TRIAC is a medium-power bidirectional thyristor designed for switching and phase control applications in AC circuits. Packaged in a TO-202 case, it is commonly used for motor control, light dimmers, and appliance switching circuits operating on 50/60Hz mains power. With its 600V blocking voltage and 3A RMS current rating, it offers reliable performance in both resistive and inductive loads.
