Can two P-N junction diodes back to back...

Can two P-N junction diodes back to back works as P-N-P transistor?

Text Solution

Verified by Experts

No, by joining two p-n junction diodes back to back, the n-region which will form the base, will be too thick and will not serve the purpose of base in a transistor.
