PG3E5SS Series
Gas Discharge Tube
Description
Prisemi GDT's are designed for a high degree of surge protection at a low cost. It operates on the gas physical principle of the
highly effective arc discharge . The PG3E5SS Series is used for protecting equipment for which higher voltage limits and
holdover voltages are necessary. Com-gaps function as switches which dissipate a mini-mum amount of energy and therefore
handle currents that far surpass other types of transient voltage protection.
Features
Very fast response time
Suitable for direct strikes
Stable performance over life
Very low capacitance
High insulation resistance
Application
Communication lines
CATV equipment
Test equipment
Data lines, power supply
Base station
Medical electronics
