What is the difference between diode and power diode

The range of forwarding voltage drop in this diode is very small approximately 0. In this mode, the diode works as a forward characteristic. If the voltage of the cathode is high than the voltage of anode, the diode performs as blocking mode. In this mode, the diode performs like the reverse characteristic.

The power diodes depending on the reverse recovery time as well as the process of manufacturing are classified into three types such as. Please refer to this link to know more about Schottky diodes. The power diodes depending on the penetration of the depletion region are reversed biased condition are classified into two types such as. These diodes are protected by using snubber circuits from the spikes of overvoltage.

This may occur while doing the process of reverse recovery. The V-I characteristics of a power diode are shown below. Once the forward voltage increases then the forward current will be increased linearly. An extremely less amount of current leakage will supply in the reverse bias condition. Hence power diodes come with various mountings for proper heat dissipation.

Differences between the power diode and normal diode are summarised below: Cut in voltage of normal diode For Si and Cut in voltage for power diode for SCR.

In a normal diode, the Heat sink is not required but in power diode conduction is more hence area or size required to dissipate more heat Heat sink is required. In the case of power diodes, semiconductor losses during switching are more as a comparison to the normal diode. The power handling capability of Power diodes is very high.
