TVS-Varistors, MOVs, is a widely used series of electrical protection products in electronic systems.The EZJ-S2YD472, one of its popular models,has wide range application field and variousworking principles.

Firstly, the EZJ-S2YD472 could be used to protect any system, including telecom, audio,video and other automotive electronics from surge, transient and ESD-induced damages.The wide range application field of the EZJ-S2YD472 provides protection from voltage spikes and over-voltage conditions. Furthermore, it provides EMI/RFI suppression to protect sensitive electronic components in the system from radio interference.

In terms of the working principle of the EZJ-S2YD472, it is a metal oxide varistor (MOV).It connects the incoming power line with the ground. When the incoming voltage or current exceeds a preset threshold, the MOV’s resistance is reduced thus allowing the excess current to be diverted safely away from the sensitive components. MOV’s are mainly used in industrial and power applications to protect from lightning, ash reparation and over-voltage.

Next, the EZJ-S2YD472 also features transient protection.Transient protection is a technique in which a low energy electrical or magnetic field dissipates the energy of a transient voltage or current before it can affect the sensitive components in the system.The EZJ-S2YD472 uses a two-stage clamping design to provide protection against high voltage transients up to 50v. The first stage provides low level protection and the second stage provides higher level protection.

Finally, the EZJ-S2YD472 also has ESD protection. Electro-static discharge (ESD) is an electrical shock that can cause system failures, component damage and even fire. The EZJ-S2YD472 features a high capacitance ESD protection diode. This helps to divert any high voltages away from the sensitive components in the system.

In conclusion, the EZJ-S2YD472 is a robust electrical protection device with a wide variety of applications. It is capable of providing surge, transient and ESD protection. Furthermore, its two-stage clamping design and its high capacitance ESD protection diode make it ideal for protecting any electrical system from damage and failures caused by unexpected power spikes, transient voltages. and electro-static discharges.
