Solid State device to replace a spark gap

Solid State device to replace a spark gap

Solid State device to replace a spark gap

(OP)
Hi
We have a circuit that uses a spark gap.  Are there inexpensive solid-state devices that could be used instead. The component needs to breakover at about 20kv and have a significant life span (automotive application)

RE: Solid State device to replace a spark gap

What is the energy level that must be discharged?  Most solid state devices would be impractical unless specifically designed for the application.  In the past, vacuum tubes could be applied, as in some radar components.  Perhaps some piezo device can convert the electric energy to mechanical energy, at that voltage level.

RE: Solid State device to replace a spark gap

The 20KV requirement is the killer.  If this is the minimum, you are out of luck.  If it is just what happens to be currently designed in thing, look at how it must function.  There are devices that can operate into the 1-3 KV range. (cost is another factor hi KV = high cost)

I suggest looking at the design concept to rethink it, rather than just (blindly?) trying to replace a component.
