triode

(ˈtraɪəʊd)

1. (Electronics) an electronic valve having three electrodes, a cathode, an anode, and a grid, the potential of the grid controlling the flow of electrons between the cathode and anode. It has been replaced by the transistor

2. (Electronics) any electronic device, such as a thyratron, having three electrodes

[C20: tri- + electrode]
