BT137 Triac 600V 8A BT137-600E

BT137 Triac 600V 8A BT137-600E 

The BT137-600E is a medium-power bidirectional TRIAC designed for controlling AC loads in a variety of electronic and electrical systems. It offers a 600 V repetitive peak off-state voltage and 8 A RMS on-state current, making it well suited for moderate power switching and phase control applications. The BT137 supports four-quadrant gate triggering, ensuring reliable operation across the full AC waveform. Packaged in a TO-220 case, it can be easily mounted and heat-sunk for improved thermal performance.
