TechnologiesThe BT169DL-A-T92-B is a unidirectional Thyristor-TRIAC from Unisonic Technologies. This device uses a TRIAC (Thyristor) to switch an electrical load in either direction, when triggered by an applied signal. It has a 400V voltage, a TO-92-3 package, and is RoHS compliant. It can be used as a high-power switch, motor-speed control, and can also be used to regulate light dimmers. The BT169DL-A-T92-B is a cost-effective solution for many applications where unidirectional switching is needed.
