About TRIACs
TRIACs (Triode for Alternating Current) are bidirectional thyristors essential for AC power control. Unlike SCRs, they conduct current in both directions when triggered, making them ideal for phase-angle control in dimmers, motor controllers, and heating systems. Their ability to switch AC loads with minimal components simplifies circuit designs.
Selecting the right TRIAC involves balancing voltage/current ratings, gate sensitivity, and commutation capabilities. Properly specified TRIACs like the BT131-600 enhance system longevity by reducing switching stress and electromagnetic interference (EMI) in AC power networks.
