thyristor

plural thyristors

1. businessA semiconductor diode having an extra "gate" terminal to switch it on.

   In calling it a "Thyristor", Mr. Warder was following a growing practice which takes account of the fact that in years to come the controlled rectifier may be made of other materials than silicon.
