Electronic Devices and Circuits
7.

Assertion (A): In design of circuit using BJT, a derating factor is used.

Reason (R): As the ambient temperature increases, heat dissipation becomes slower.

Both A and R are true and R is correct explanation of A
Both A and R are true but R is not a correct explanation of A
A is true but R is false
A is false but R is true
Answer: Option
Explanation:

Increase of ambient temperature lowers the heat dissipation capacity.

Therefore derated operation of BJT is necessary lest BJT should be destroyed.
