Reverse saturation current of a diode

Options

  1. Ais independent of temperature
  2. Bincreases with increase in temperature
  3. Cdecreases with increase in temperature
  4. 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.
