DZ4J180K0R Working Principle

The DZ4J180K0R is a Zener diode array, which operate in a slightly different way than traditional Zener diodes. The Zener diode array provides a simpler and more cost-effective way of controlling sudden voltage spikes or drops on an electrical system, compared to using separate Zener diodes. The device uses a low-resistance parallel series connection to enable a fast and reliable response indicating an input surge or drop.

The Zener diode array has two parts: a series of Zener diodes connected in parallel and a field-effect transistor (FET). When the input voltage exceeds the Zener breakdown voltage, the series of Zener diodes will begin to conduct and the positive voltage will be applied to the FET gate, which will switch and allow current to flow. This reverse current flow will be limited to a safe level and the voltage will be regulated to the specified level. The reverse current will be limited to the rated peak and the maximum hold current.

When the input voltage drops, the Zener diodes will no longer conduct, the FET gate voltage will become negative and the FET will turn off, preventing current from flowing. The DZ4J180K0R is designed to regulate the voltage so that it remains within a specified range, allowing the protected electronic device to operate reliably.

Conclusion

The DZ4J180K0R is a popular diode array that is used in a wide variety of consumer and industrial applications. It is a Zener diode array that operates using a low-resistance parallel series connection, allowing it to quickly and reliably protect an electronic device from sudden voltage spikes and drops. By limiting the reverse current to a safe level, the DZ4J180K0R effectively regulates the voltage to remain within a specified range.
