The minimum potential difference between...

The minimum potential difference between the base and emitter required to switch a silicon transistor ON is approximately?

A

1 V

B

3 V

C

5 V

D

4.2 V

Text Solution

Verified by Experts

The correct Answer is:
A
To switch on the transistor, the emitteri- base collector-base junction is reverse biased. The cur-off voltage for silicon is ~1V, so to switch on a silicon transistor a potential difference of 1V approximately is required between the base and emitter.
