The module has a very strong current capability with a regular value of 30A and maximum of 40A. The peak reverse voltage is 1200V and the junction temperature of the rectifier module is 150°C.

VS-HFA30PB120-N3 Application Field

VS-HFA30PB120-N3 rectifier module is commonly used in different fields, such as telecom power supplies, computer power supplies, server power supplies, emergency lights, and other systems that requires ac-dc conversion. The rectifier module also helps to improve the current and voltage stability for boost power supplies. In addition, it can be applied for three-phase rectification, filter capacitor charging, and boost power supply.

Therefore, VS-HFA30PB120-N3 rectifier module is an ideal device for low operation loss of power supplies, low practical efficiency of power supplies, and low heating of power supplies due to its fast recovery characteristics. With the large current capability, it is also suitable for large power area and can lower the installation cost.

VS-HFA30PB120-N3 Working Principle

The VS-HFA30PB120-N3 rectifier module contains three active components, which are three fast recovery diodes with a reverse recovery time of less than 10 nanoseconds. When it is active, the diodes are used to inject current into the output, thus providing a forward bias voltage.

When the forward bias voltage is higher than the minimum operating voltage, the rectifier module starts its action and let current flow from the positive pole of the anode to the negative pole at the cathode. This allows the VS-HFA30PB120-N3 to convert ac signals into dc signals. The rectifier module also has an integrated shunt that can help reduce energy losses while the diode conducts current.

In the meantime, the VS-HFA30PB120-N3 also has a high stability on current and voltage that make it suitable for the most current-consuming applications. Besides, the advanced passivation technology and press proof elements improve its strong temperature resistance, which significantly increases product reliability.

Conclusion

In conclusion, VS-HFA30PB120-N3 is a 3-phase fast recovery rectifier module suitable for applications that require ac-dc conversion and boost power supply. The module has the advantage of high current supply, long-term operation stability, and robust temperature resistance. Therefore, it can improve the current and voltage stability for power supplies and reduce their energy losses.
