TVS - Varistors, MOVs

V150LA20CPX360 is an ultra-low leakage current, compact multi-function metallized polyester film varistor equipped with an integrated silicon diode. This type of varistor can offer a combination of high surge capability and low leakage current for a variety of applications, and is typically used in a wide range of commercial and industrial equipment. Such usage can include circuit protection, lightning protection, transient voltage surges, and EMI/RFI filters.

Application Field

The V150LA20CPX360 is ideally suited for use in automotive and telecom applications. It has found application in cars, trucks, and construction vehicles, where it is used to protect against electrical surges and other transient voltage spikes. It is also commonly used in telephone and cable systems, where it helps protect against sudden voltage surges and flickering. Additionally, it is employed in communication systems, computers, and instrumentation, where it offers circuit protection, transient suppression, and EMI/RFI filtering.

Working Principle

The V150LA20CPX360 functions by clamping transient voltages at an amplitude above the rated varistor voltage and diverting the transient current away from the circuit and ground. This is achieved by combining its integrated silicon diode with its high surge rate capability. This surge suppression device can absorb a wide range of transient voltages, with a current rate that can be up to 1KA. When a transient voltage is present, the varistor acts as a switch, connecting the energy of the transient voltage to ground. This dissipates the energy of the transient, thus providing circuit protection.

The V150LA20CPX360 further features an internal open frame which contracts the area of exposed active material, reducing the capacitance along with the insertion loss characteristics. It also mitigates losses due to air movement, resulting in a higher surge capability. Additionally, the varistor has been designed to offer low leakage current for a wide range of operational temperatures, making it perfect for use in industrial and automotive applications where reliability is essential.

In summary, the V150LA20CPX360 is an ultra-low leakage current, compact multi-function metallized polyester film varistor equipped with an integrated silicon diode. It is commonly used in automotive and telecom applications, where it offers circuit protection, transient voltage suppression, and EMI/RFI filtering. It functions by connecting the energy of transient voltages to ground, thus dissipating the energy and providing circuit protection. Additionally, its low leakage current makes it perfect for industrial and automotive applications where reliability is essential.
