TVS – Varistors, MOVs

B72205S0151K101 is one of many Surge Protective Devices (SPDs) that include Varistors (VDRs) and Metal Oxide Varistors (MOVs) that are used to protect against electrical surges and spikes. These devices are designed to provide maximum protection from dangerous voltage transients, electrical noise, and electro-static discharges (ESD). They have a wide range of application fields in a variety of markets including industrial, military, and consumer electronic devices that require protection from lightning, short circuits or faulty wiring.

Application Field for B72205S0151K101

The B72205S0151K101 is typically used in industrial, automotive and consumer electronics to provide protection from electrical transients, electrical noise, and electro-static discharges (ESD). It’s designed to protect power supplies, personal computers, and appliances, as well as Signal integrity protection for electronic interfaces. B72205S0151K101 is a high-performance device that often used as a voltage protector in applications ranging from motors, pumps, circuit boards, and telecommunications equipment.

Working Principle

Varistors and MOVs work on a very simple principle; when the voltage across the device moves beyond a certain range, the current rating also changes abruptly. Varistors and MOVs use a semiconductor material which limits the current flowing through it at any given time. As the voltage applied across the device increases, the current rating within the device also increases until a maximum current rating is reached.

When the maximum current rating is reached, the current begins to drop as the circuit disconnects. This allows the voltage applied to the device to decrease to its usual normal operating range. The voltage transient that is received is clamped to a safe level, preventing damage to the circuit due to the high-voltage surge.

Varistors and MOVs are often used in conjunction with one another in more sophisticated devices such as surge protective devices. When used together, they can provide much better protection against surges and transients than using either one in isolation.
