VE24P00151K

Transient voltage suppression (TVS) components protect valuable assets, such as electronics and circuit boards, from the electrical noise that can often cause damage. Varistors and metal-oxide varistors (MOVs) are two of the most common types of TVS components. The VE24P00151K is an example of a MOV, and it is designed for equipped with surge protection with high surge capability and low leakage current. This article looks at the application field and working principle of the MOV VE24P00151K.

Application Field

The VE24P00151K is designed as an overvoltage protection device for pulse currents. It is designed for protection against lightning strike surges. Specifically, the MOV VE24P00151K is designed for protection from transient overvoltages caused by lightning strikes on long overhead transmission lines, and it is suitable for use in outdoor cable TV systems. The MOV VE24P00151K can protect these systems from surges that come from distant lightning strikes.

Working Principle

The MOV VE24P00151K is designed as an active component. It is a specialized type of semiconductor device that uses a metal-oxide-semiconductor field-effect transistor (MOSFET). The device has two terminals, the anode and the cathode, which are connected to the power supply. When there is an overvoltage, the device will be triggered and will block the surge. The MOV VE24P00151K is a nonlinear device, which means that it behaves differently depending on the incoming voltage. When the voltage is low enough, the device acts as an open circuit. When the voltage is high enough, the device behaves as a short circuit.

When the device is in a short circuit state, the current becomes infinite, and the device will be equipped with a fuse. The fuse will then blow, protecting the power supply from the surge. The MOV VE24P00151K also has a temperature coefficient, which means that it will be triggered when the temperature rises and it will block the surge. This helps to protect the device from overheating.

Conclusion

The MOV VE24P00151K is designed as an overvoltage protection device for pulse currents. It is designed for use in outdoor cable TV systems that risk damage from transient overvoltages caused by lightning strikes. The device works by using a MOSFET to block the surge when the voltage rises too high, and it also has a temperature coefficient helps to protect the device from overheating. Overall, the MOV VE24P00151K is an effective way to protect devices from transient overvoltages.
