Ideal Diode Equation
Ideal diode equation
In a p-n junction diode, the current I can be expressed as I=I0(exp(eVKBT)−1), where I0 is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, KB is the Boltzmann constant (8.6×10−5eV/K) and T is
What is an ideal diode?
An ideal diode is a diode that acts like a perfect conductor when voltage is applied forward biased and like a perfect insulator when voltage is applied reverse biased. So when positive voltage is applied across the anode to the cathode, the diode conducts forward current instantly.
What is ideal and real diode?
Ideal diode starts allowing the electric current, once the forward voltage is applied. However, the real diode behaves differently. The real diodes do not allow the electric current, if the forward voltage is less than the cut-in voltage.
