The BT169GEP is a one-way Thyristor TRIAC manufactured by Infineon. Thyristors are a type of semiconductor device that can control and regulate AC current and voltage in electronic circuits. This Thyristor TRIAC can handle a maximum voltage of 600V and is packaged in a TO-92-3 RoHS package. The TRIAC is a bidirectional device, meaning it can work both forwards and backwards allowing it to be used in applications such as controlling LED dimmers, industrial motor speed controllers, AC switch circuits, and AC heaters. The BT169GEP is suitable for use in applications where high switching speeds are required and low gate sensitivities is not an issue.
