DZ23C20-HE3-18

Introduction

DZ23C20-HE3-18 is a type of zener diode arrays, which is composed of 18 diodes (with 3 series and 6 parallel) that are intended to protect circuits against overvoltage, undervoltage and overcurrent, and are designed for high speed switching applications. It has a rated current of 8A, a rated reverse voltage of 3.2V, and a peak current of 10A.

Application Field

DZ23C20-HE3-18 has the following application fields mainly:

1. Power Supplies: DZ23C20-HE3-18 is ideal for use in power supply designs with high speed switching, as its peak current is 10A. It is used for voltage protection and current protection, preventing power supply circuits from excessive voltage, undervoltage and current.

2. Computer Peripherals: DZ23C20-HE3-18 is used as a voltage protection device in computer peripheral devices, such as hard disk drives, DVD drives, and so on.

3. Automotive Electronics: Due to its high current rating, DZ23C20-HE3-18 can also be used in automotive electronic devices, such as anti-lock braking systems, power steering systems, etc., as these systems require high current protection against overvoltage, undervoltage and overcurrent.

Working Principle

When DZ23C20-HE3-18 connects to a power supply, diodes in the arrays will turn on depending on the voltage. If the voltage is higher than reverse voltage, the diode will turn on and reduce voltage before it goes the the load. When the voltage is lower than reverse voltage, the diode will not conduct, so the load will always get the desired amount of voltage. In addition, when the load current is higher than its rated current, DZ23C20-HE3-18 also can protect the circuit, quench the current and turn off the circuit to protect it.

Conclusion

As a type of zener diode arrays, DZ23C20-HE3-18 has the application fields of power supplies, computer peripherals and automotive electronics. Its working principle is relatively simple, while still achieving the purpose of overvoltage, undervoltage and overcurrent protection. It is widely used in various circuits.
