The MAC97A8 with TO-92-3 TRIACs is a RoHS compliant device manufactured by Kang Yang. It is a thyristor (triode for alternating current) designed for use in AC switching, motor control, and other loads. The TO-92-3 package is a three-pin device that has one gate and two main terminals. The main terminals are an anode and a cathode, while the gate is used to control the conduction of the triac. It has a rated current of 8A, a static dV/dt of 500V/us, and a peak on-state voltage of 800V. The device is designed to operate at temperatures ranging from -40°C to 125°C.
