Introduction

SE20FGHM3/I is a diodes – rectifiers – single product which belongs to a wide range of components with different applications in the field of electronic engineering.
In this article, the focus will be on the application areas of SE20FGHM3/I as well as the basic working principle.

Application Field of SE20FGHM3/I

SE20FGHM3/I has a wide range of applications, mainly in the area of power supply circuits. It is used in DC/DC converters, battery chargers and pico power supply applications. Additionally, SE20FGHM3/I can be used in the motor controlling applications.

SE20FGHM3/I is also used in rectification and protection circuits such as transportation and telecommunication systems, photovoltaic systems, inverters, and high voltage power supply systems. Its reverse voltage is 20V and its current capacity is 400mA. These features make it suitable for a number of applications.

The diode is capable of withstanding 3000V surge peak reverse voltage and has an average forward current rating of 150mA. This allows it to be used in wider range of applications including consumer electronics, automotive and industrial applications.

Working Principle of SE20FGHM3/I

SE20FGHM3/I is a signal diode with a very precise switch characteristics. It acts as a direct current (DC) controlled switch, carrying current in one direction only and blocking it in the reverse direction – hence its name “diode”.

SE20FGHM3/I is made of a p-type semiconductor and an n-type semiconductor. The p-type semiconductor is connected to the anode terminal, while the N-type semiconductor is connected to the cathode terminal. Electrons are drawn towards the n-type semiconductor, creating a potential barrier between both semiconductors and preventing any current from flowing in the reverse direction.

When a forward voltage is applied to the diode, current flows in one direction only, from the anode to the cathode terminal. This is due to the electric field created by the forward voltage between both terminals which provides the energy to get the electrons through the potential barrier. The forward current determines the speed of the electrons in their movement through the diode.

On the other hand, when a reverse voltage is applied to the diode, current will not flow due to the potential barrier created by electrons. This makes the diode act as an open-circuit, blocking current directly.

Conclusion

SE20FGHM3/I is a high quality diode which provides a wide range of applications including DC/DC converters, battery chargers, photo-voltaic systems, rectification and protection circuits, and motor controlling. It has a reverse voltage of 20V and a current capacity of 400mA, providing a reliable and durable solution for different applications.

The diode operates by creating a potential barrier between both terminals which prevent current from flowing in the reverse direction. When a forward voltage is applied, current can move freely from the anode to the cathode terminal.
