Introduction to DZ23C4V7-G3-18The DZ23C4V7-G3-18 is a type of diode array produced by Zener. This type of diode array delivers high accuracy, low standby current and high voltage transient protection. The DZ23C4V7-G3-18 can help provide precise voltage protection for applications such as switching power supplies, computers and other sensitive electronics.Application Field and Working PrincipleThe DZ23C4V7-G3-18 diode array is ideal for use in switching power supplies, computer systems, audio and video devices and other sensitive electronics where precise voltage protection is desired. It can operate from 7.5V up to 18V and can provide up to 500mA of continuous current. The DZ23C4V7-G3-18 also provides protection against transient voltage spikes and power surges.The working principle of the DZ23C4V7-G3-18 is based on the simple diode principle of forward biased operation and reverse biased operation. The diode array consists of two separate arrays connected in series. The two arrays are connected together in an alternating fashion with the positive of one connected to the negative of the other and vice versa. When forward biased, the two arrays conduct simultaneously and allow current to flow in one direction and not the other. When reverse biased, the two arrays are blocked and prevent current from flowing.The reverse biased voltage breakdown voltage of the DZ23C4V7-G3-18 is around 5V. Once this threshold is exceeded, the underlying diodes within the array start conducting and provide overvoltage protection. This prevents damage to the device that the diode array is connected to.ConclusionThe DZ23C4V7-G3-18 diode array is a reliable and accurate way to provide overvoltage protection to equipment connected to a switching power supply, computer system or other sensitive electronic device. The device is capable of conducting a continuous current of up to 500 mA and has a reverse biased voltage breakdown voltage of around 5V. This provides ample protection from transient voltage spikes and power surges.
