Effect of Temperature on the V-I Characteristics, Ideal diode
Effect of Temperature on the V-I Characteristics
Reduction in the cut-in voltage takes place with increase in temperature.
The breakdown voltage increases with increase in temperature.
Reverse saturation current increases with increase in temperature.
For even rather small forward bias voltages the exponential is very large because the thermal voltage is very small, so the subtracted ‘1’ in the diode equation is negligible and the forward diode current is often approximated as
What is an ideal diode?
An ideal diode is a perfect conductor with zero voltage drop in the forward bias direction…
…and a perfect insulator in the reverse bias direction.
