The RK8xxK, RK8xxH, and RK8xx series are 3-quadrant triacs designed for general-purpose operation. They are suitable for applications such as light dimmers, motor speed controllers, static relays, heating regulation, AC switching, and induction motor starting circuits. These triacs offer high current density due to double mesa technology and glass passivation, making them recommended for use on inductive loads and for phase control.
