Question

When a p-n-p transistor is operated in saturation region, then its ___________.

• A. Base-emitter junction is forward biased and base-collector junction is reverse biased.
• B. Both base-emitter and base-collector junctions are reverse biased
• C. Both base-emitter and base-collector junctions are forward biased
• D. Base-emitter junction is reverse biased and base-collector junction is forward biased.

Answer 1

Answer: (C)

Both base-emitter and base-collector junctions are forward biased

In active and saturation modes, current in a PNP flows from emitter to collector which implies that the emitter must generally be at a higher voltage than the collector. Both Emitter Base and Base Collector junctions of the transistor are forward biased
