TVS (transient voltage suppressors) are a type of electronic device used in the protection of a circuit from high voltage and high energy electrical transients. Varistors, also referred to as Voltage Dependent Resistors (VDRs), are the most commonly used type of TVS. Varistors and MOVs (metal oxide varistors) are one type of these electronic components. The V20E550PL2T1 is a surface mount varistor and MOV combination device.

The V20E550PL2T1 is a semiconductor device designed to protect against overvoltage transients and high-energy transients from electrical noise, surge, ESD (electro-static discharge), EFT (electrical fast transient) sources and other similar threats. It provides an economical solution to help protect sensitive and valuable electronic components from these types of threats with its high surge clamping, low capacitance, and low leakage current characteristics. The V20E550&PL2T1 components are designed for high reliability applications and feature an internal metal oxide layer to reduce leakage current, additional protection against high-energy electrical transients, and good impulse response.

The main application field for the V20E550&PL2T1 is automotive electronics, industrial electronics and consumer electronics. It is often used to protect integrated circuit (ICs), printed circuit boards (PCBs), transistors, discrete components, and sensitive electronic products. It is also used to protect a wide variety of power supplies, radios, telecommunication products, computer peripherals, motor controls, data converters, consumer electronic products, and more.

The working principle of the V20E550&PL2T1 device is based on its two components, the varistor and the MOV. When a voltage greater than the breakdown voltage of the device is applied, current will start to flow through the device. The presence of the MOV layer on the device helps to reduce the amount of current that can flow through the device. This decreases the overall current flow and helps to protect the components from excessive current. The varistor acts to lower the breakdown voltage (VBR) of the device by redirecting current to a more streamlined path. This reduces the voltage spike across the components of the circuit and helps to protect them from damaging transients.

The V20E550&PL2T1 device can provide reliable over-voltage protection for a wide range of applications. This is done by combining a varistor and MOV which provide controlled clamping for electricity surges, ESD, EFT, and electrical noise. The internal metal oxide layer helps to reduce leakage current and the high surge clamping helps to prevent damage to the connected circuitry. In summary, the V20E550&PL2T1 device is an effective and economical solution for overvoltage protection for a wide variety of applications.
