Question

If holding current of an SCR is 6 mA then its latching current should be ___________

(a) 4 mA

(b) 5 mA

(c) 12 mA

(d) 6 mA

I got this question during an online interview.

This interesting question is from Solid-State Devices topic in division Introduction to Solid-State Devices of Electric Drives

Answer 1

Right option is (c) 12 mA

To elaborate: If holding current of an SCR is 6 mA then its latching current should be 12 mA. The latching current is 2-3 times more than the holding current.
