The V20120CHM3/4W rectifier diode is part of a popular series of diodes from Vishay Semiconductor, created for low power applications. This rectifier contains two chips inside, each with dual Schottky diodes with common anode connections that share a single cathode. It is therefore used for many standard diode rectifier applications, such as flyback and buck converters, as well as in DC-DC converters, synchronous rectifiers, and power supplies. This diode can be used for both AC and DC current, and is made with a surface mount device (SMD) package for easy circuit assembly.

The V20120CHM3/4W is a 100V, 50mA diode and features a maximum forward voltage drop of just 0.35 volts. This low voltage drop allows it to be used in applications where efficiency is critical. The device also has an Avalanche energy rating of 20 mW and an operating temperature range of -65 to +150°C.

Another great feature of the V20120CHM3/4W is its very low forward and reverse capacitance, which allows faster switching speed. This makes it an ideal choice for applications requiring high-speed switching, such as motor control circuits.

In terms of its application field, the V20120CHM3/4W rectifier diode is widely used in general electronics, automotive, telecommunications, computer, and aerospace applications as well as in power inverters and power supply circuits.

The working principle of a rectifier diode is based on the fact that they are semiconductors and can only let current flow in one direction. They are made of PN junction semiconductors which have one p-type semiconductor layer and one n-type semiconductor layer. When a voltage is applied to the PN junction, the junction is said to be forward biased and current will flow through the diode. On the other hand, when no voltage is applied to the PN junction, it is said to be reverse biased and no current will flow through it. Thus the components of the V20120CHM3/4W rectifier diode works on this principle only, allowing it to act as fast switching, low drop rectifiers.
