TVS (Transient Voltage Surge Suppressors), Varistors, and MOVs (Metal Oxide Varistors) are popular components found in computer and electronic circuit designs. Their primary function is to protect a circuit from short-term voltage transients, such as computer spikes or lightning strikes, which could cause irreversible damage to the circuit’s components. A TMOV20R200E is a specific type of MOV designed to be used in a variety of applications. This article will provide an overview of its application field and working principle.

A TMOV20R200E is a Metal Oxide Varistor (MOV) designed for commercial and industrial applications. Its rated working voltage is between 59 and 370 volts, and it can withstand transient surges up to 20,000 A/s. Its temperature range is between -40 and +85°C, making it suitable for outdoor and high-temperature environments. It is also shockproof and vibration-resistant, making it suitable for applications requiring robustness. It has a low leakage current design, with a maximum allowable leakage current of 0.04 µA at 20 V peak. This MOV offers protection against temperature cycling, surges, and short-circuits.

The working principle of the TMOV20R200E is fairly straightforward. The MOV works by diverting any excess voltage away from the protected circuit and towards ground, thus preventing damage. When a voltage transient passes through the MOV, the Varistor undergoes a rapid increase in electrical resistance, blocking current flow to the protected circuit and diverting it away. This process allows the MOV to absorb and dissipate the transient energy without damaging the protected component or the MOV itself.

The TMOV20R200E is most commonly used in automated electronic systems, such as robotics, industrial machinery, communications systems, and electronic automotive components. In these systems, the MOV absorbs any sudden voltage spikes and diverts them away from the sensitive components, preventing damage to the system. Additionally, the TMOV20R200E is often used in home security systems, home theater systems, home automation systems, surveillance systems, and in medical devices. It is also suitable for use in television antennas, UPS and voltage regulator units, and inverter/converter systems.

In conclusion, the TMOV20R200E is a Metal Oxide Varistor designed for commercial and industrial applications. Its rated working voltage is between 59 and 370 volts, and it can withstand transient surges up to 20,000 A/s. Its primary function is to protect a circuit from short-term voltage transients, such as computer spikes or lightning strikes, which could cause irreversible damage to the circuit’s components. Its working principle involves diverting any excess voltage away from the protected circuit and towards ground, thus preventing damage. This MOV is most commonly used in automated electronic systems, home security systems, home theater systems, home automation systems, and surveillance systems.
