V180ZA05PX2855

The V180ZA05PX2855 is a device typically classified as a TVS - Varistors, MOVs.

A varistor, also known as a metal oxide varistor (MOV), is a semiconductor device designed to protect against excessive voltage surges in electricity supplies. An MOV is essentially a voltage-dependent resistor with a resistive non-linear property in its resistance versus voltage evaluation. These surge protectors or voltage-dependent resistors operate by dissipating excessive energy from unexpected voltage spikes, and thus is used in electrical and electronic circuits to protect them from damage, premature failure and other adverse effects.

The V180ZA05PX2855 varistor has a rated voltage of 180V AC and a maximum clamping voltage of 545V. This TVS also boasts a low leakage current and thermally-stabilized construction. The device is also designed with an industry-standard common-mode surge capability with an ultra low-capacitance rating.

The function of this device is to protect sensitive circuits from voltage and current spikes. It performs this function by allowing a limited amount of current to flow to the protected circuit, thus preventing spikes from entering and damaging the sensitive electronics. In addition, the V180ZA05PX2855 also provides noise filtering and EMI/RFI protection.

The device is typically found in a variety of applications such as medical equipment, telecommunications, aircraft, process control, signal processing, and other micropower systems. The V180ZA05PX2855 helps protect these systems from voltage fluctuations caused by lightning strikes and other power disturbances, thus ensuring a safe operating environment.

The working principle of the V180ZA05PX2855 is that it is designed with a low resistance path to conduct most of the transient energy. This is due to its p-n junction diode elements that are capable of conducting current resulting in lower breakdown voltage. The voltage dependent resistor remains in a state of ready-to-conduct mode and gets activated only when the voltage in the circuit across it is above the rated voltage. During this situation, the MOV acts like an arc-gap making it possible for current to pass through to the protected circuit.

In the event of an unexpected rise in voltage, the V180ZA05PX2855 will act like a switch and open the circuit, while providing ground shunt protection. This helps to reduce the voltage and current peaks that could otherwise damage the system. This helps the device protect electronic components and circuits from damage or failure.

The V180ZA05PX2855 is an excellent protection device for all types of electrical and electronic circuits and systems. It provides superior protection against spikes in voltage and current, as well as noise and EMI/RFI filtering. Due to its compact design and low leakage current, it can be used in a variety of applications and still maintain its reliable performance.
