TVS - Varistors, MOVs are devices that have the function of protecting circuits against voltage transients. This article will discuss the application and working principle of the V27RA8X2749 protection device.

V27RA8X2749 are designed to protect electronic components from the effects of overvoltage and tansient voltage pulses. It is a bidirectional varistor whose MOVs offer overvoltage protection for circuits connected directly to the AC power line, which is particularly useful in powered-only systems. The device also features a self-resetting fusing function in case of an overvoltage incident. It offers a wide operating temperature range, allowing the device to be used in a variety of environments.

The device features a bidirectional varistor structure which is based on two circuits, connected in series. The first circuit is a pair of normally-on, normally-off metal-oxide (MOV) varistors which offer overvoltage protection. The second circuit is a pair of normally-off, normally-on varistors which absorb energy from overvoltage and tansient voltage pulses.

The V27RA8X2749 provide a very reliable protection against overvoltage and transient voltage pulses. They have an outstanding thermal capacity, withstanding temperatures up to 135°C. In addition, the device has a fast recovery time when exposed to transient voltage pulses. It also has a very low leakage current with a resistance of up to 30Ω.

The V27RA8X2749 can be used in a variety of application areas. It can be used in power supplies, lighting fixtures, communication systems, industrial equipment, automotive systems, battery charging systems and many other applications. In addition, the device is also suitable for use in applications that require very low leakage current, such as medical equipment.

The V27RA8X2749 are able to detect iic AC power lines and protect against dangerous overvoltage and transient voltage pulses. Once an overvoltage incident is detected, the device will self-reset and no further action is required. It is also easy to install, with only a few connections required.

To summarize, the V27RA8X2749 is an ideal device for protecting circuits against overvoltage and transient voltage pulses. It offers a wide operating temperature range and can be used in a variety of application areas. It has a fast recovery time, low leakage current and can self-reset when an overvoltage incident is detected. Overall, the V27RA8X2749 is an effective and reliable protection device for circuits.
