The NHP620MFDT3G is a general purpose multi-function diode array with a variety of applications. This type of diode array is designed to provide protection from unwanted transient electrical pulses when connected in smoothing circuits. This can help to maintain power supply and reduce interference.

This diode array, comprising of three terminals and six diodes, is a special purpose product developed by NXP Semiconductors. The NHP620MFDT3G’s principal application is as a field-effect transistor (FET) switch for controlling electrical circuits to provide over voltage protection, reverse polarity protection and ground fault protection, depending on the application.

A diode array is a type of diode which is designed to block or limit the current flowing through it via junction diodes. The NHP620MFDT3G is modeled after an array of junction diodes connected externally in parallel or series, which are designed to create a voltage-controlled switch. This type of diode array provides less resistance and higher current capability than a single diode, allowing the device to handle a higher voltage range.

When the voltage applied to the input of the NHP620MFDT3G exceeds the rated voltage, the device limits the current flow by redistributing it. The diode array provides voltage protection and is used to protect sensitive components from voltage spikes. When an over-voltage condition exists, the NHP620MFDT3G will limit the voltage to the specified level by way of a high impedance that is suitable for the application.

As well as providing overvoltage protection, the NHP620MFDT3G can also be used to create a voltage-controlled switch by employing a function circuit. This type of circuit is designed to control the current passing through the diodes, thus providing reverse polarity protection, ground fault protection and frequency synchronization, depending on the application. This type of circuit also improves the frequency response of the diodes by providing the required switching speed for voltage regulation.

The NHP620MFDT3G is a general purpose multi-function diode array which provides protection from overvoltage events, reverse polarity protection, ground fault protection and frequency synchronization. This diode array is designed for applications which require high current handling capabilities, fast switching speed and good reliability. The NHP620MFDT3G is an ideal choice for applications which require very low resistance and higher current handling capability, such as in electronic ballast systems, filter bypass systems, AC/DC converters and photovoltaic applications.
