BT136 600V 4A Triac Thyristor TO 220 Package

BT136 600V 4A Triac Thyristor TO 220 Package 

The BT136 is a compact bidirectional TRIAC designed for low-to-medium power AC switching and phase control applications. Rated for 600 V repetitive peak off-state voltage and 4 A RMS on-state current, it is ideal for controlling small to moderate AC loads. Its bidirectional conduction and four-quadrant gate triggering make it suitable for driving AC loads in both halves of the waveform. The device comes in a TO-220 package—making it easy to mount and, if needed, attach a heat sink for improved thermal management.
