TVS (Transient Voltage Suppressor) devices, also known as varistors, MOVs, and more, are designed to protect sensitive electronic equipment from voltage transients induced by lightning and electrostatic discharge (ESD). The VDRH20X680BSE is a transient voltage suppression device commonly used in aerospace, automotive, and other applications that involve the use of low energy physics circuits. The device\'s application field and working principle are discussed in this article.

The VDRH20X680BSE is designed for use in ECAPS (Electronic Capacitive/Arc Protection Systems). This is a type of protection circuit designed to suppress voltage transients in high-energy physics applications, such as those found in electric power grids, automotive systems, and aerospace systems. ECAPS, as the name implies, uses two components – a capacitor and an arc resistor – to limit the voltage and current flowing through the circuit. The VDRH20X680BSE acts as an active component, shunting the high-energy transient signals away from the circuit, thus providing circuit protection.

The VDRH20X680BSE has a maximum peak repetitive voltage of 680 volts, with a breakdown voltage of 511 volts. The device is constructed from two main parts, a top plate and a bottom plate. The bottom plate is made of a polymeric Film. The top plate contains a terminator plated of Gold and Palladium or Nickel and Palladium, providing low resistance between the top and bottom layers.

When a transient voltage event occurs, the VDRH20X680BSE device starts to dissipate power as a result of the high voltages and currents. This dissipated power is proportional to the voltage and current on the device. As the transient voltage rises, the device quickly begins to provide protection by clamping the voltage to the device’s breakdown voltage. This reduces the magnitude of the transient voltage or current, thus protecting the sensitive circuit components from being damaged due to overvoltage.

The VDRH20X680BSE is highly recommended for use in aerospace, automotive, and other applications due to its high-speed response time, high power rating, and low capacitance. This device is also designed for high reliability, making it perfect for mission-critical applications. The device is also easy to install, making it the perfect choice for applications where convenience and speed are essential.

In summary, the VDRH20X680BSE is an ideal choice for applications that require fast and reliable protection against voltage transients, such as those found in high-energy physics applications, electric power grids, automotive systems, and aerospace applications. The device’s rugged construction and fast response time make it a highly reliable choice for these applications. The device is also easy to install and provides a high level of protection without introducing any additional components to the circuit.
