Step 1:

The forward voltage drop is $\"\"$

The forward bias current is $\"\"$ .

Room Temperature $\"\"$ .

Absolute temperature $\"\"$ .

The idea law of diode : $\"\"$ .

$\"\"$ is the forward bias current.

$\"\"$ is the reverse saturation current.

q is the absolute value of the electron charge = 1.60217657 × 10^-19 c.

V_f is the forward voltage drop.

k is the Boltzmanns constant = 1.3806488 × 10^-23 m² kg s^-2 K^-1

T is the absolute temperature.

$\"\"$ is the ideality factor.

Let us consider the diode to be made up of silicon then $\"\"$ .

$\"\"$

Solution:

The reverse saturation current is $\"\"$ .
