Question

Which of the following is true for a pnp transistor in saturation  region?

(a) CB junction is reversed bias and the EB junction is forward bias

(b) CB junction is forward bias and the EB junction is forward bias

(c) CB junction is forward bias and the EB junction is reverse bias

(d) CB junction is reversed bias and the EB junction is reverse bias

I have been asked this question in examination.

My doubt is from BJT Circuits at DC in chapter Bipolar Junction Triodes (BJTs) of Electronic Devices & Circuits

Answer 1

Correct option is (b) CB junction is forward bias and the EB junction is forward bias

The best explanation: Whether the transistor in npn or pnp, for it be in saturation region the EB junction must be forward bias the CB junction must be forward bias.
