Question

How much times reverse saturation current will increase if temperature increases 15^oC?

(a) 2.52

(b) 4.62

(c) 4.12

(d) 2.82

The question was asked by my college professor while I was bunking the class.

My question is based upon Characteristic Equation of Diode-2 topic in portion Diode Circuit of Analog Circuits

Answer 1

Right option is (d) 2.82

The best explanation: The equation relating final reverse saturation current (Io2) to initial reverse saturation current (Io1) is given by

Io2 = 2^(∆T/10)Io1

Where ∆T is temperature change

Ratio is 2^15/10 = 2.82.
