Introduction

The S2JHE3_A/I is a single rectifier diode with a high forward current and its application in motor drives, power supplies and inverters is commonplace. This type of diode offers a low forward voltage drop and has a high current rating. Additionally, this component can save on power losses when used in applications involving high frequencies.

Working Principle

The S2JHE3_A/I is a component made with a P-N junction. When there is a forward bias (external power supply or battery) to the diode, the diode allows current through the component. This occurs because the negative charge of the P-side of the device repels the electrons from the N-side which allows the mobile charge carriers to cross the junction easily and quickly leading to a high current rating.

Applications

The S2JHE3_A/I diode is widely utilized in motor drives because of its high forward current and low forward voltage drop. This type of diode is designed for AC-DC applications and act as a rectifier in the commutation process. This diode can be used in several different commutation stages in motor drives such as induction, reluctance and permanent magnet as long as the durations of the commutations do not exceed 10 ms. Additionally, this component is used in combination with inverters in order to control the motor power; in this type of automotive applications the S2JHE3_A/I diode is used in order to reduce the inrush current and voltage ripple during the commutation process. This particular diode can also be used in applications related to computers, electronic circuits and switches. Finally, due to its low forward voltage drop and high current rating, this component can be used as a part of a surge protection system that is able to absorb transient overvoltages in order to protect the whole system from any damages.

Conclusion

To conclude, the S2JHE3_A/I is a single rectifier diode that is designed for AC-DC applications. A major advantage of this component is its low forward voltage drop and high current rating; thanks to the P-N junction it is made from, it is capable of allowing a high current through an external power supply or battery. Furthermore, this type of diode has a variety of uses such as in motor drives, computers, switches and surge protection systems; all of these types of applications require the use of diode with a high current and low forward voltage drop.
