TVS (Transient Voltage Suppressor) devices, Varistors, and MOVs (Metal Oxide Varistors) are essential components used in a variety of circuits. These components are designed to protect circuits from being subjected to high levels of transients or surges caused by overloads and other such electromagnetic disturbances. ZV30K1812T801N is a 2-lead SMD type TVS that utilizes a Zinc Oxide (ZnO) film as the non-linear element, and falls under this category of devices. Its application field as well as its working principle will be discussed in this article.

Introduction to ZV30K1812T801N

ZV30K1812T801N is a TVS (Transient Voltage Suppressor) device manufactured by NEC. It is a surface mount component, and comes encapsulated in a SOT-523B package. It comprises of an epoxy resin body and has 6 terminals: 2 for mounting, 2 for solder, and 2 for external connection. This device has a maximum power rating of 600W (at 1.5ms), a maximum peak pulse current of 30A (at 8/20µs), a maximum clamp voltage of 18V, and a breakdown voltage of 12V. It is designed for use in circuits that require protection against high-energy transient or surges caused by overloads and EMI.

ZV30K1812T801N Application Field

ZV30K1812T801N is designed for industrial applications, such as in industrial control, consumer electronics, and power supplies. It is ideal for circuits that require protection from transients or surges that may be caused by overloads or electromagnetic interference. It is also suitable for protection of circuits sensitive to electrical noise, such as optical sensors, switching regulators, and high-speed CCD cameras.

It is important to note that this device is not suitable for permanent overvoltage protection. It is designed for circuit protection against transient voltage for a specified duration after which the device needs to be replaced with a new one for circuit protection. Furthermore, it is not suitable for use in circuits where the peak power and the number of pulses in the transient voltage is unknown.

ZV30K1812T801N Working Principle

ZV30K1812T801N utilizes a Zinc Oxide (ZnO) film as the non-linear element which enables it to protect circuits from transient voltage. When the voltage across its terminals exceeds the breakdown voltage (12V in this case), the ZnO film will start to conduct, thus providing protection to the circuit from overvoltage conditions. The peak pulse current that it can handle is limited by its internal resistance and the peak power rating (600W).

This component works in the same way as other TVS devices, but uses a different non-linear element for its operation. It is important to note that due to its size and internal element composition, it may not provide protection in circuits subject to high-energy transients, and it is advised to use other, more robust devices for such applications.

Conclusion

ZV30K1812T801N is a two-lead SMD type TVS device, manufactured by NEC. It is designed for industrial applications, and is ideal for circuits requiring protection from transients or surges caused by overloads and EMI. It utilizes a Zinc Oxide (ZnO) film as the non-linear element, and this enables it to provide protection to the circuit against overvoltage conditions. However, it is not suitable for circuits subject to high-energy transients, and it is advised to use more robust devices for such applications.
