WebJan 2, 2024 · • 4. Holding current is defined as a minimum value of anode current below which it must fall for turning off the thyristor.. • 5. The TRIAC is a bidirectional thyristor with three terminals. It is used extensively for the control of power in ac circuits. • 6. The DIAC is an n–p–n or p–n–p structure with a uniformly doped layer. WebHitachi Energy's gate turn-off thyristor is optimized for low conduction losses. The typical on-off switching frequency is in the range of 200 - 500 hertz. Production of GTOs commenced in the mid 1980s. A GTO is a thyristor that can be turned off by applying a current to the gate in the reverse direction to that required to turn it on.
