The P4200SB Gas Discharge Tube (GDT) from SEMIWARE is a small and highly reliable component designed to protect telecom, data, signal processing, telecommunications, and control circuits against damage due to electromagnetic susceptibility (EMS) or transient voltage spikes. This device, which complies with the Restriction of Certain Hazardous Substances (RoHS) Directive, is available in an SMB (Surface Mount Box) design which makes it easy to install in tight spaces. The P4200SB has a leakage current of less than 0.06 mA, a voltage drop of 4100 Vdc, and an interrupt current of 12kV (8kA). Each unit also features high current (>2µA) pulse withstand performance for up to 8A lasting up to 50ns.
