CR08AS-12B is a three-terminal device manufactured by KEXIN, which contains two thyristors – two TRIACs – in a single package. This device is packaged in a SOT-89 RoHS (a small outline transistor) package, which is a surface mounted package suitable for leaded or lead-free soldering. Two of the terminals (MT1 and MT2) are connected when a current of gate current flows from gate to MT2. The third terminal (MT2) provides a common connection for both thyristors. When the gate current is removed, the thyristors switch off. The CR08AS-12B is suitable for AC control applications. Features of the CR08AS-12B include a breakover voltage, gate trigger current, and surge intensity of VBO 35V, IGT 10mA, ITSM 50A.
