Working Principle

The ZV30K1210T301N is composed of semiconductor material consisting of zinc oxide granules mixed with a metal oxide varistor (MOV). A metal oxide varistor is a nonlinear voltage-dependent resistor, composed of a ceramic material and a metal compound. Under normal operating conditions, the circuit current flows through the MOV, causing electrons to move from one end of the component to the other. When an overvoltage event occurs, the electrons move back to the other end as the voltage potential of the device changes, causing the current to be diverted from the component. This effectively dissipates the potentially damaging voltage and prevents the current from reaching sensitive components.

Conclusion

In summary, the ZV30K1210T301N is a high-voltage transient protection device which can be deployed in a variety of power and signal line protection applications. Its semiconductor material is composed of zinc oxide granules mixed with MOVs, which make it highly effective at suppressing voltage transients and protecting sensitive components. It is suitable for use in a wide variety of automotive, industrial, and consumer electronic applications, making it an ideal choice for engineers looking to optimize safety in their designs.
