The V150LU20BPX10 is a particular type of TVS (Transient Voltage Suppressor) device widely used for preventing electrical overvoltage damage to sensitive electronics. It is also known as a Varistor or MOV (Metal Oxide Varistor). This articles will explain the application field and working principle of the V150LU20BPX10 device.

Application fields:

The V150LU20BPX10 is typically used in high-end electronic products which have to meet rigorous EMC (electromagnetic compatibility) standards and also endure extreme electrical conditions, such as electrical surges or lightning strikes. These devices are regularly found in telecom, automotive, military and industrial applications. The V150LU20BPX10 features low voltage rating of 150V and 20A of maximum surge current capacity, making it suitable for applications which require reliable protection of sensitive electronic components from undesired high voltage or high current surges.

Working principle:

The V150LU20BPX10 is a nonlinear device which works by dissipating electrical energy through a metal oxide varistor element. Initially, when the input voltage is lower than the device’s breakover voltage, the V150LU20BPX10 is a low impedance non-conducting path, allowing normal current flow while blocking any unwanted voltage. When the voltage level applied to the V150LU20BPX10 device rises above the breakover voltage, it quickly drops its impedance and thus becomes a conducting path. In this way the V150LU20BPX10 absorbs most of the energy of the surge, dissipating it through the oxide layer in the device in the form of heat.

The V150LU20BPX10 is usually mounted between the power source and the protected circuit to form a very effective overvoltage protection scheme. The device typically consists of two terminals: anode (+) and cathode (-). When installed, the anode should be connected to the power source terminal which is likely to experience the surge and the cathode should be connected to the protected device (usually called GND for grounding).

The V150LU20BPX10 is designed to never fail, even in the most extreme environment conditions. The device has high surge handling capacity and can protect components from high voltage surges without damaging them. Moreover, the device is also able to filter out noisy power spikes and keep the application’s power source free from interference.

In conclusion, the V150LU20BPX10 is a versatile and reliable MOV device which can be used for a wide range of applications, from automotive to military devices. It is a robust and cost-effective way to protect sensitive electronic components from overvoltages and power surges.
