A diode is simply a pn junction but its applications are extensive in electronic circuits.

Ideal characteristics of diode. Under a forward bias condition this should be about 7 volts. Ideal diode consists of two terminals. Conclusion diodes allow current to flow freely in one direction while limiting flow in the opposite direction.

The pn junction region of a junction diode has the following important characteristics. The positive end or positive terminal of the diode is called anode and the negative end or negative terminal of the diode is called cathode. Ideal diodes do not have a breakdown voltage.

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. Positive terminal and negative terminal. When the diode is forward biased it acts like a closed switch as shown in the figure below.

Additionally the ideal diode has zero resistance to current flow in one direction and high resistance in the opposite direction. Usually a diode operates either in forward or reverse biased condition. Usually a diode operates either in forward or reverse biased condition.

Then there is the reverse voltage drop. An ideal diode also acts like a switch. Reverse biased means that if there is a negative voltage that is relative only to the direction of voltage flow indicated being applied to the diode there is no current flow and the diode acts as an open circuit as shown in figure 11 c.

A semiconductor may be doped with donor impurities. Semiconductors contain two types of mobile charge carriers holes and electrons. The holes are positively charged while the electrons negatively charged.

So when positive voltage is applied across the anode to the cathode the diode conducts forward current instantly. Whereas if the diode is reversed biased it acts like an open switch as shown in the figure below. Ideal diodes include unlimited forward current when any forward voltage is applied.

An ideal diode means a perfect diode which has all properties in their perfect sense without any flaws. Ideal diodes do not have a threshold voltage. Three important characteristics of a diode are first of all the forward voltage drop.
