TVS (Transient Voltage Suppressor) Varistors, MOVs (Metal Oxide Varistors), and other surge suppressors are used in a variety of applications in order to limit and/or suppress transient voltages and surges.

The B72205S0500K211 is a multi-layer piezo film and silicon-based silicon varistor surface mount component. This component is capable of absorbing relatively large amounts of energy, making them well suited for use in a variety of different applications, including automotive, telecommunications, consumer electronics, industrial, and other equipment.

The B72205S0500K211 varistor has limited power dissipation capability, so they are limited to applications where the transient voltage disturbance is low and the transient current is low. This limitation makes them well suited for use in applications with lower transient voltages, such as in telecommunications and consumer electronics equipment.

The working principle of the B72205S0500K211 varistor is based on its construction. Inside, it contains a thin film of ceramic material and a layer of silicon-based, silicon varistor material. When connected across a voltage source, the B72205S0500K211 varistor creates a field across the two layers of material. When a current is present, the electric field generated across the two layers of material causes the ceramic material to expand in a proportional manner. This expansion changes the capacitance of the B72205S0500K211 varistor, creating a voltage drop across the varistor. In other words, the B72205S0500K211 varistor acts as an voltage clamp whose job is to limit or suppress the amount of voltage which can flow from one side of the varistor to the other side.

The B72205S0500K211 varistor is usable over a wide temperature range and is suitable for mounting on a printed circuit board (PCB). The device is rated for a continuous voltage of 500 volts and for a peak pulse voltage of 14KV (at 8/20 μs). The B72205S0500K211\'s maximum peak current is 16 A and its maximum dissipated energy at 4A is 1.0J. Its temperature coefficient ranges from -40°C to +100°C. The device meets the requirements of RoHS and WEEE.

The B72205S0500K211 is a widely used device for the protection of telecommunications, consumer electronics, automotive, industrial, and other applications from transient voltages and surge related disturbances. It is used to protect against surges in DC or AC lines, including automotive wiring, and other applications. The B72205S0500K211 varistor is a cost-effective solution for protecting sensitive equipment from damaging transient voltage.
