ERZ-E07A271CS

Gas Discharge Tubes (GDTs) are a type of surge protection technology that is widely used in the industry today. They offer a high level of protection against transient voltage surges, and they are often seen in power distribution systems, domestic and commercial appliances, as well as telecom systems. The ERZ-E07A271CS is a GDT operating with a Threshold of 400V installed in a wide range of applications.

The ERZ-E07A271CS is typically used in power systems, telecom systems, computer systems, and general-purpose circuitry. It is often used to protect sensitive equipment from overvoltage, transient voltage surges, and electrostatic discharge (ESD). The GDT works by providing a low-impedance path to ground when a surge or over voltage triggers it, thus allowing the surge to bypass the protected circuitry. This helps to ensure that equipment is protected against surges that can occur during power outages or other unexpected events. The device also helps to reduce the risk of fires caused by overvoltage in electrical installations.

The ERZ-E07A271CS is a single line GDT that can provide up to 5,000A of protection against surges up to 400V. It has a capacitance of 12pF, a high-speed response time of 25ns, and a voltage break-over of 82V. The device also offers excellent ESD protection and can withstand up to ±35kV of air discharge and ±28kV of contact discharge. Additionally, the device is resistant to voltage transients of up to 1.2kV without suffering any damage. This makes it a suitable choice for protecting sensitive electronic components in a wide variety of applications.

The working principle of the ERZ-E07A271CS can be best described as a “sudden breakdown of air”. When the device is exposed to an overvoltage, the air within the device breaks down, turning it into a low-impedance path to ground. This enables a quick and safe transfer of the surge current from the circuit to the device, thus protecting the circuit. The device is designed to recover quickly and resume normal operation once the surge has passed.

In terms of safety, the ERZ-E07A271CS is certified to UL1449, the standard for surge protective devices. This makes it a reliable and safe choice for power systems, telecom systems, computer systems, and general-purpose circuits. Overall, the ERZ-E07A271CS is an ideal choice for protecting sensitive equipment and circuits from transient voltage and surge threats.
