SMD5050 Surge Protector Ceramic Gas Discharge Tube 5050 SMD GDT Protection Circuit for Power Supplies
Description of SMD5050 Gas Discharge Tube
SMD5050 Gas Discharge Tubes (GDT) series provides high levels of protection against fast rising transients caused by lightning disturbances. Offered in a miniature surface mount package, it has a surge rating of 3KA/2kA 8/20μs.
SMD5050 GDTs are high voltage (1000-3600V) components designed for surge protection and high isolation applications. It is also suitable for applications for which bias voltage or signal levels of several hundred volts are normally present. SMD5050 GDTs can be used in conjunction with MOVs (Metal Oxide Varistors) to provide superior protection performance for AC applications.
