TRIACs

TRIACs for full-cycle AC switching: BTA, BTB, BT136, BT139, MAC, and Z0107 series. Packages TO-220, TO-220F (isolated), TO-92. Filter by RMS on-state current Itrms 0.8-40 A, repetitive peak voltage Vdrm 400-800 V, gate trigger current Igt, and dV/dt. Used in light dimmers, heater and pump control, AC motor speed regulation, solid-state relays, and phase-cut controllers for appliances. Often paired with opto-triac drivers (MOC3021, MOC3041) for isolation.
