Question

By what percentage the reverse saturation current increases with 10 C rise in the temperature.

(a) 25%

(b) 12.5%

(c) 50%

(d) 7%

This question was addressed to me during a job interview.

My question comes from The Temperature Dependence of P-N Characteristics topic in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

The correct answer is (d) 7%

The explanation is: As the temperature to the P-N junction diode increases the mobility of charges increases thus increasing the current, the reverse saturation current increases by 7% with 10C rise in temperature and doubles with every 100C rise in temperature.
