The MAC97A6 with TO-92-3 is a TRIACs ROHS manufactured by Kang Yang. It is a three-terminal bidirectional semiconductor switch designed for use on alternating current (AC) circuits. The MAC97A6 is a 800V, 2A (Max.) device available with 4 different gate current (IGT) ratings, from 5mA up to 630mA. It has low gate control power, low thermal resistance, and high commutation capability, which make it ideal for static switching and phase control applications like light dimming, motor speed control, etc. It is compliant with the Restriction of Hazardous Substances (RoHS) regulations and is halogen-free.
