S4020L,Silicon-Controlled Rectifier,TO-220

The S4020L is a Silicon-Controlled Rectifier (SCR) developed for phase control applications, including motor speed controls, heating systems, and industrial AC power switching. With a peak reverse repetitive voltage (VRRM) of 600V and a continuous forward current rating of 20A, this SCR is optimized for efficient and reliable power control.

Designed for high inrush conditions, the S4020L handles a non-repetitive surge peak on-state current of 300A at 60Hz, making it robust against power fluctuations. The low forward voltage drop (Vf) of 1.6V minimizes energy losses, ensuring high efficiency in power conversion systems.

Encased in a TO-220 package, this SCR offers excellent thermal management and easy integration into high-power designs. With a low reverse leakage current (Ir) of 10µA, the S4020L is a reliable choice for solid-state AC switches, power regulators, and industrial automation applications.
