Application Field

The MMBZ27VDA-E3-18 Zener diode array is used in a variety of applications, such as protecting sensitive circuitry from harmful voltage spikes, in applications such as computer motherboards and automotive electronics. It can also be used to control the output level of a power supply by regulating the input voltage. The diode array can also be used in power circuits to prevent spikes and surges from affecting circuit operation. Additionally, the Zener array can be used as an over-voltage protection device in industrial equipment.

Working Principle

In order to understand how the MMBZ27VDA-E3-18 works, it is important to understand how the components that make up the array interact with one another. The array consists of three Zener diodes connected in parallel, each having its own breakdown voltage. These Zener diodes are connected in series with an inductor. When the input voltage exceeds the breakdown voltage of one of the Zener diodes, it begins to conduct and the excess voltage is then dissipated across the parallel diodes. This prevents the voltage from rising unevenly, which could cause damage to the connected circuitry. Additionally, the inductor allows for slow and gradual dissipation of the excess voltage, which helps to protect the connected circuit.

The MMBZ27VDA-E3-18 array of Zener diodes is capable of handling a wide range of voltages, making it a viable option for many applications that require low power consumption. The diodes are capable of handling up to 36V, allowing for a wide range of applications where it might be needed. With its ability to dissipate excess voltage, the MMBZ27VDA-E3-18 array can provide protection against voltage spikes, making it an ideal choice for a variety of industrial, automotive, and computer applications.
