A reverse voltage guard (RVG) is an important component for protecting sensitive electronics against transient over-voltage events, usually occurring in power lines or other power supply applications.

RVG applications are widely used in many areas, ranging from industrial, automotive, and consumer electronics to communication, medical and aerospace applications. RVGs are used to protect sensitive equipment from overload and electrostatic discharge (ESD) events. By not allowing high-voltage or ESD to pass through, RVG’s help keep sensitive components safe from damage.

RVGs are usually constructed using a single semiconductor device, most commonly a diode. The most common type of diode used in an RVG is a single junction silicon rectifier diode. A single rectifier diode can be used to protect up to 10 Watts of power. The diode is typically placed in series with the load, often in a low−value resistor, to limit current. When a reverse voltage is applied to the diode, it quickly turns on, blocking the reverse voltage from reaching the load.

Diodes have a very low voltage drop, and they are able to handle relatively large amounts of reverse power without being damaged. In addition, they are relatively inexpensive, easy to install, and require minimal maintenance. When a reverse voltage is applied, the diode turns on and power cannot pass through to the load.

RVG’s can also be used to protect against over-voltage events, such as power surges or lightning strikes. By using RVG’s with a voltage limiter, a low voltage is maintained on the load, preventing damage from occurring. RVG’s are also useful in applications requiring protection from noise, such as telecommunications equipment.

RVG’s are known for their reliability and robustness. They are often used in harsh and extreme environments where they are subjected to extreme temperatures, shock, and vibration. In addition, they are often used in applications where maintenance is expensive or difficult.

The working principle of an RVG is quite simple. When a reverse voltage is applied, the diode turns on and the power cannot pass through to the load. The diode is designed to quickly turn on, blocking the reverse voltage from reaching the load. By using an RVG with a voltage limiter, the voltage is maintained at a safe level, protecting the load from damage caused by over-voltage events. The single diode RVG is a relatively simple and cost-effective solution for protecting sensitive electronics.

RVGs are a key component in many different industrial, automotive, and consumer applications. In addition, they are used in industries such as telecommunications, medical, and aerospace. RVGs can be used to protect sensitive components from damage caused by transient over-voltage events, often occurring in power lines, power supply, and other applications.

In summary, reverse voltage guard (RVG) application fields and the working principle is relatively simple and straightforward. RVG\'s are constructed around a single diode, usually a silicon rectifier diode, and is connected in series to the load and current-limiting resistor. RVGs are used to protect sensitive equipment from overload and ESD events, and from over-voltage events such as power surges or lightning strikes. RVG’s are reliable, robust, and require minimal maintenance and are used in many different industrial, automotive, and consumer applications.
