SH - Series Gas Discharge Tube 5kA Square GDT Surface Mount Type
≤0.7pF Capacitor
SH Gas Discharge Tubes (GDT) series provides high levels of
protection against fast rising transients caused by lightning
disturbances. It has a surge rating of 5kA, 8/20μs. Offered in a
Squared Surface Mount package, which helps to make pick and place
on PCB process easier.
This GDT series is perfectly suited for broadband equipment
applications. The GDT’s low off-state capacitance is compatible
with high bandwidth applications and this capacitance loading value
does not vary if the voltage across the GDT changes.
SH Gas Discharge Tube (GDT) series are specifically designed for
protection of electrical, multimedia, and communication equipment
against over voltage transients in surface mount assembly
applications.
