To an ideal semiconductor diode (p-n junction) the current flowing when directed biased depends on the voltage and also the temperature as in the following formula:
Formula 1
Diode current:
Where:
I is direct current in amperes (A)
Irmax is the blocking current or saturation current in amperes (A)
V is applied voltage in volts (V)
Vr is the termic potential in volts (V)
e = 2.71828
