DZ23C4V7-E3-18 belongs to the family of Zener Arrays from Diodes Inc. It is a 4-diode array of ultra low voltage Zener diodes, not exceeding the clamping voltage of 18 volts.

The DZ23C4V7-E3-18 has a wide range of applications, including reverse and transient voltage suppressors, clamping applications for signal lines, and power supply protection circuits. It also can be used for overvoltage protection and ESD protection. It is built in a SOT-363 compatible surface mount package.

The working principle of the DZ23C4V7-E3-18 is the same as any typical Zener Diode. When a reverse polarity voltage is applied to the two terminals of the diode, that is to say, the diode is forced to conduct electrons in the reverse direction, a counter electromotive force is generated in the diode. This force will make the voltage across the diode stabilizes at the Zener voltage of the diode, no matter what is the size of the input voltage. This Zener voltage that is determined by the properties of the PN junction and the type of semiconductor materials called the Zener breakdown voltage. The higher the Zener breakdown voltage, the more typical Zener action.

The two terminals of the DZ23C4V7-E3-18 are connected through four diodes in parallel, which can reduce the “on-state” resistance and the junction capacitance of the diodes. Thus, it will achieve a lower clamping voltage and faster response time compared to other similar devices. In addition, it has a larger power dissipation capability than the discrete Zener diodes with the same ratings.

In conclusion, the DZ23C4V7-E3-18 is a very useful device in many applications and it provides a robust solution for circuit protection. Its compact package, low clamping voltage and fast response time makes it an ideal choice for many applications.
