Over-temperature protected triac and protection method |
摘要 |
A triac circuit comprises a triac having first and second main terminals (MT1,MT2) and a gate terminal and a thyristor connected between one of the main terminals (MT1,MT2) and a control terminal of the triac circuit. The thyristor is used to prevent turn on of the triac when it has turned on by temperature induced leakage currents. |
