The minimum potential difference between the base and emitter required to switch a silicon transistor ON is approximately
Updated On: Jun 20, 2022
- 1 V
- 3 V
- 5 V
- 4.2 V
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
To switch on the transistor, the emitter-base junction of a transistor is forward biased while collector-base junction is reverse biased. The cut-off voltage for silicon is $1\,V$, so to switch on a silicon transistor a potential difference of $1\,V$ approximately is required between the base and emitter.
