What is the ratio of holding current to lathing current in a thyristor?

Answers

Answered by PiyushSinghRajput1

Usually, latching currents are double or triple of holding currents for higher rating thyristors. They may fall as low as 0.4. But is usually dependent on temperature and driving load. One 20A (500V) thyristor used commonly is BT152 and it has the ratio 1.67.
