(Pack of 5) BT131 600V 1A Triac

(Pack of 5) BT131 600V 1A Triac 

The BT131 is a low-power bidirectional TRIAC designed for small AC switching and control tasks. Rated for 600 V repetitive peak off-state voltage and 1 A RMS on-state current, it’s suitable for switching low-power AC loads such as small lamps, relays, and control circuits. The device supports four-quadrant gate triggering, which allows it to be triggered reliably in all polarities of AC voltage and current. Coming in a compact through-hole package, the BT131 is ideal for space-constrained designs and general purpose AC control.

This listing is for a pack of 5 TRIACs, making it convenient for multiple projects or spares.
