WebA Silicon Controlled Rectifier (SCR) is a unidirectional semiconductor device that can be triggered into conduction by applying a positive gate current. It led to tremendous advancements in power semiconductor devices. They … WebThe holding current value IH (refer to AN302 for holding current) is linked to the latching current value IL. For the most TRIACs (rated current lower than 40 A), the IL value is higher than the IH value. The IL /IH ratio is related to the TRIACs current rating, as shown Table 2. Table 2. Approximate ratio between I + +--+-QII QI QIII QIV V T I ...
