BTA12 600V 12A Triac

BTA12 600V 12A Triac 

The BTA12 is a medium-power bidirectional AC switch (TRIAC) designed for versatile AC power control and switching applications. Rated for 600 V repetitive peak off-state voltage and 12 A RMS on-state current, it is suitable for controlling moderate AC loads in both consumer and industrial environments. The device supports four-quadrant gate triggering, allowing dependable trigger performance across all polarities of AC voltage and current. Housed in a TO-220 package, the BTA12 can be easily mounted with a heat sink for efficient thermal management.
