The BT131-600 with Thyristors - TRIACs TO-92 (TO-92-3) RoHS manufactured by Haoruijia is a three-terminal semiconductor device with standard TRIACs features. It is a bidirectional thyristor, used for controlling the flow of current in both directions, with a switch-like action. This device is optimized for low gate power drive and has a higher threshold than other TRIACs, making it suitable for light load control applications. It can be triggered with gate currents as low as 10µA and voltages up to 900V, making it perfect for high-power AC line voltage switching applications such as motor speed and light intensity control circuits. This device is also RoHS compliant, which ensures it is free of hazardous substances and environmentally safe.
