⚙️ Typical Applications
-
AC mains switching — e.g. heaters, lamps, resistive loads.
-
Inductive load control — motors, fans, solenoids (the TRIAC is rated for inductive loads and has dv/dt robustness).
-
Light dimmers, motor-speed controllers, AC power controllers.
-
General-purpose AC switching in home appliances, industrial equipment, and automation circuits.
