?The BTA41-800CW is a Thyristor TRIACs manufactured by CJ and compliant with RoHS standard. It is a three-terminal semiconductor device that is mainly used for the control of AC power. It is a bidirectional (controllable from both sides) switch with two independent gates, allowing it to be triggered using pulses or analog signals. The BTA41-800CW is designed for switching and phase control applications such as power controllers, rectifiers, and Home Appliances. It has a maximum achievable blocking voltage of 800V, a continuous current rating of 35A, and a maximum surge current of 101A. This part also has surge capability, making it well suited for applications that require fast reaction time and repeatability. Its TO-3PK package makes it suitable to use in low-cost, discrete designs. Lastly, the BTA41-800CW is RoHS compliant, ensuring the absence of hazardous materials and minimizing its risk to human health and the environment.
