Reverse saturation current of a diode
Options
- Ais independent of temperature
- Bincreases with increase in temperature
- Cdecreases with increase in temperature
- Dmay increase or decrease with increase in temperature depending on the semiconductor
Correct answer
B. increases with increase in temperature
Step-by-step solution
With the rise of temperature, the density of minority charge carriers increases due to breaking of some covalent bonding in a semiconductor in reverse biased condition. So, the reverse saturation current increases.
