Question

When the gate signal from a thyristor is removed, it will remain in its forward conduction mode. This characteristic of thyristor is called

• A. Get-on
• B. Ever conducting
• C. Latching
• D. Off-blocking

Hint:

The latching characteristic allows a thyristor to remain on even without gate input—useful for reducing gate drive complexity.

Answer 1

The Correct Option is C

A thyristor, once turned on by a gate pulse, continues to conduct even after the gate signal is removed, as long as the anode current is above the holding current. This property is known as latching, which means the device "latches on" and remains in conduction without continuous gate triggering.
