#1 Gas discharge tube.

Post by pre65 »

What is a gas discharge tube ?

How would this work compared to a 90v Zener or 90v regulator tube ?

Oo I got "site unavailable"


I'm guessing gas discharge tube per se is for protecting equipment against high Voltages, not for regulation.

They are deigned to work like crow bars and used to protect Telecom equipment from things like lightning strikes.

Link now works....

^ What he said ~ according to its data sheet it might hold 80V ('glow Voltage') but, as with varistors (VDR 'suppressors') for similar purposes, I can foresee a power dissipation problem for continuous operation. It being only tiny. :?:
