BTA41 600V 40A Triac
The BTA41 is a high-power bidirectional AC switch (TRIAC) designed for demanding AC power control applications. With a 600 V repetitive peak voltage rating and 40 A RMS on-state current capability, it is built to handle heavy loads in both industrial and consumer systems. The device offers four-quadrant triggering, allowing it to be driven effectively in all polarities of current and voltage. Encapsulated in a TO-247 package, the BTA41 provides excellent thermal performance and can be mounted to a heat sink for enhanced power dissipation.
