Diodes - Rectifiers - Arrays

The GHXS030A120S-D4 is a single-channel integrated rectifier array used to control the flow of current in an electrical circuit. The rectifier array combines the rectifier diode, protective diode, and limiter diode functions in a single package, and features front-end protection to protect against transient voltage.

Application Field

The GHXS030A120S-D4 is primarily used in various applications related to energy conversion, including but not limited to: AC/DC converters, DC/DC converters, switch power supplies, adapters, and smps controllers. Its protection capability makes it suitable for use in harsh environment such as automotive, industrial, and other industries.

Working Principle

The GHXS030A120S-D4 contains two rectifier diodes, one protective diode, and one limit diode. The two rectifier diodes, D1 and D2, can be used for AC to DC rectification, allowing the device to draw current from an AC source with varying intensity or frequency. The protective diode, D3, protects the device from excessive voltage caused by transient voltages, while the limit diode, D4, provides a restricted limit to the voltage and current entering the device.

To control the direction of the current flow, the GHXS030A120S-D4 contains two control terminals, labelled S and G. When the S terminal is connected to a positive voltage, the current is allowed to flow from the anode side to the cathode side of the diodes. Conversely, when the G terminal is connected to a positive voltage, the current is allowed to flow from the cathode side to the anode side of the diodes.

The GHXS030A120S-D4 also features several protection features, such as the Transient Voltage Suppression (TVS) diode, which guards against damage to the device caused by electrical disturbances. The TVS diode is also capable of suppressing high-frequency noise to minimize interference in the device\'s operation.

Conclusion

The GHXS030A120S-D4 is a versatile rectifier array which offers superior performance and protection against excessive voltage. Its front-end protection and noise suppression features make it suitable for use in a variety of applications related to power conversion.
