TVS - Varistors, MOVs, are a type of transient voltage surge protection device designed to protect sensitive electronic components and systems from voltage spikes occurring due to lightning strikes, incorrect wiring, or electrostatic discharging. The TMOV14RP140E is a transient voltage surge suppressor for high-voltage transients protection that is designed specifically to protect customer\'s electronic equipment from lightning damage caused by high voltage transients and power surges.

The TMOV14RP140E shows excellent noise suppression performance and wide-range voltage operating characteristics. It is specifically designed to protect AC power leads or data lines carrying DC or AC signals. Its compact size and wide operating temperature range make it suitable for a variety of applications in the industrial, military, and consumer markets. It is also designed to provide excellent protection against overvoltage, surge, and other high voltage transient events.

This surge protection device features an ultra-wide operating voltage range with a maximum clamping voltage of 14V. It also includes a peak current rating of 140A and a peak power rating of up to 1.2kW. The device is designed to work in applications requiring high speed response and low clamping voltage. Furthermore, its low capacitance ensures high speed data transmission with minimal electromagnetic interference (EMI) emissions.

The TMOV14RP140E has a wide range of application fields, such as machine control boards, automotive electronics, computers, communication systems, medical devices, and power electronics. In particular, it is widely used in the protection of contemporary automotive and industrial electrical systems, including motor control systems, onboard diagnostics, and powertrain electronics.

The TMOV14RP140E working principle is based on the principle of Metal Oxide Varistor (MOV) construction. In this context, the MOV consists of a non-linear ceramic composed of zinc oxide and blends of other metal oxides that are formed into a disc and then encapsulated in an environmentally-sealed, epoxy resin-filled case, and then enclosed in a metal shell. When placed in a circuit or system, it acts as a voltage-sensitive resistor and produces an instant clamping action whenever it detects voltage levels that exceed the internal breakdown voltage of the varistor. That is to say, when the voltage rises above the rated breakdown voltage of 14V, the MOV will immediately reduce current and dissipate the energy of the transient. In this way, it will effectively clamp the voltage, clamping time being in the range of a few nanoseconds.

In summary, the TMOV14RP140E is a high-performance transient voltage surge suppressor used for protection against voltage surges and spikes occurring due to lightning strikes, incorrect wiring, or electrostatic discharging. It is designed for applications requiring high speed response and low clamping voltage and is widely used in the protection of various electronic components and systems. It works based on the Metal Oxide Varistor (MOV) principle with an ultra-wide operating voltage range of 14V and a peak current rating of 140A.
