BT169D TO-92 SCR (Thyristor) 600V 800mA

BT169D TO-92 SCR (Thyristor) 600V 800mA

The BT169D is a unidirectional SCR (Silicon Controlled Rectifier) thyristor designed for low trigger current applications. With a peak off-state voltage rating of 600V and an RMS on-state current of 800mA, it is suitable for low to medium power AC/DC control applications.

Thanks to its TO-92 package, the BT169D is ideal for compact circuit designs. It is widely used in dimmer circuits, motor speed control, power switching, triggering circuits, and industrial control applications. Its low gate trigger current allows direct driving from microcontrollers and logic-level circuits.
