It is a switch.
The hydrogen gas allows ionization to occur easier.
It is non linear.
It is used for things like pulsed radar. Also, as a crowbar, for cases when relays cannot open fast enough, this is triggered to shunt the voltage.
It remains latched till the current goes below a holding current.
It's like an SCR.
It has x-ray warnings because the voltage it can handle is sufficient that the electrons cause emission when they hit the anode..

That is not a problem!, hydrogen thyratrons have extremely fast turn on and can switch very high currents, they are in most cases faster than solid state alternatives, this one can switch currents of up to 500A at a rate of 2500A/us.
The problem in building a class D amp with these is that they turn off slowly as the plasma need to break down.

We use it as a comparator with zero power consumption. The design is from the stone age and creates a delay for a remanens relay. A small and well functioning solution. No need for batteries or big caps.- Status
