GIB1402HE3/81 is a single rectifier diode, with high reverse withstanding voltage, surge capability and lower series resistance. This makes it ideal for general purpose use which includes power supply, free-wheel and polarity-protection applications. In this article, we discuss the application fields and working principle of GIB1402HE3/81.

Application Fields

GIB1402HME3/81 rectifier is equipped with axial P.C. board and low V.F. These features make it suitable for all general-purpose diode applications and ideal for the designs of TO-220, power and switching packages. Temperature range of operation extends from -40℃ to +125℃.

The single rectifier is widely used in PFC (Power Factor Correction), for both AC-DC and DC-DC converters. It is also used in automotive applications such as power windows, door locks, and back-up alarms.

In addition, GIB1402HE3/81 can also be used directly in many other industry applications including solar panels, LED lighting, automotive electronics, AC-DC adapters, one-way current blocking, motor control, or motor deceleration.

Working Principle

When the anode is more negative by one diode forward voltage drop than the cathode, that diode turns-on, allowing current to flow. The reverse voltage depends on the type of material used and the size of the diode. If the voltage requirement exceeds the reverse voltage rating of the diode, the diode will be damaged. When the diode is in the forward direction, it behaves as a closed switch, allowing current to flow through in order to produce the desired outputs.

In addition to its single rectifier capabilities, GIB1402HE3/81 is designed to provide reverse polarity protection for other components. When the voltage of the application exceeds the rated breakdown voltage of the diode, it acts as a reverse polarity protection by blocking current from passing back into the system.

The surge capability of the GIB1402HE3/81 allows it to allow current to surge back and forth through the diode, even at high voltages. This feature makes it ideal for applications requiring short duration surge current protection. GIB1402HE3/81 has a low series resistance which allows the diode to handle pulse currents at high frequency with minimal voltage drop and power loss.

The GIB1402HE3/81 provides superior transient protection compared to other generic rectifier diodes. It is also equipped with a mechanical capacitor which reduces noise and EMI (Electromagnetic Interference) levels.

Conclusion

GIB1402HE3/81 is a single rectifier diode with high reverse withstanding voltage, surge capability and low series resistance. The single rectifier is used in a wide range of industry applications like PFC (Power Factor Correction), AC-DC and DC-DC converters, solar panels, LED lighting, automotive electronics and motor control. It offers superior transient protection and mechanical capacitor which reduces noise and EMI levels.
