The first SCR was developed in late 1957. Power semiconductor devices are broadly categorized into 3 types:

1. Power diodes
2. Transistors
3. Thyristors

Power diodes
1.3Power diode:
Diode is a two terminal P-N junction semiconductor device, with terminals anode (A) and cathode (C).


The symbol of the Power diode is same as signal level diode.
If terminal A experiences a higher potential compared to terminal K, the device is said to be forward biased and a forward current will flow from anode to cathode. This causes a small voltage drop across the device (<1V) called as forward voltage drop(Vf), which under ideal conditions is usually ignored. By contrast, when a diode is reverse biased, it does not conduct and the diode then experiences a small current flowing in the reverse direction called the leakage current. It is shown below in the VI characteristics of the diode.
