Meaning and Definition
A gas-filled electronic tube used as a high-speed switch or relay, containing a hot cathode and one or more anodes, controlled by a grid.
A type of controlled gas‑discharge tube (often containing mercury vapour or an inert gas) that can conduct very large currents, historically important in industrial electronics, radar modulators, and early computing circuits.

- Confusing with 'thyristor' (the modern semiconductor device).
- Using it as a general term for any vacuum tube.
FAQ
Frequently Asked Questions
It is a type of gas‑filled tube, not a hard vacuum tube. The gas allows it to conduct much higher currents.
In museums, vintage radio equipment, old industrial controls, or in some specialised high‑voltage pulse applications where its unique characteristics are still required.
Solid‑state devices like SCRs and triacs are smaller, more reliable, require no warm‑up time, and are cheaper to manufacture.
No. Unlike a vacuum triode, a thyratron acts essentially as an on/off switch; once triggered, the grid loses control until the current is interrupted.
A gas-filled electronic tube used as a high-speed switch or relay, containing a hot cathode and one or more anodes, controlled by a grid.
Thyratron is usually technical (historical electronics/engineering) in register.
Thyratron: in British English it is pronounced /ˈθaɪrətrɒn/, and in American English it is pronounced /ˈθaɪrəˌtrɑːn/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: THYratron = THYristor (its solid‑state successor) + electron tube. It's the tube ancestor of the thyristor.
Conceptual Metaphor
A 'triggerable floodgate' for electricity: once the grid triggers conduction, current flows freely until interrupted externally.
