Assertion (A): Power transistor has lower switching time than SCR

Reason (R): Power transistor has greater switching time than SCR

[A]. Both A and R are correct and R is correct explanation of A
[B]. Both A and R correct but R is not correct explanation of A
[C]. A is correct but R is wrong
[D]. A is wrong but R is correct

Answer: Option D


Power transistor does not have high rating.

Power transistors have higher operating frequency view lower switching losses. Also the reverse recovery time is smaller amounting to lower switching time. I think option C is correct for this question.

What is the use high dv/dt rating?

Power transitor are faster than SCR.

I think the Transistor has an advantage in SCR in terms of time so it should be c because the lower the value the fastest switching time.
