In addition most often the will have simple RC circuitry for pulse control of the gate.

Mike is correct. Thyristors, or SCR are essentially gate controlled diodes. That is, without a gat signal applied, they will not conduct. Once a gate signal is applied, the function just like a diode until there is zero current or a reverse bias is forcibly applied

Thyristor is the generic name for SCR's (silicon controlled rectifiers) and Triacs, which are used for switching and controlling AC power - they can be turned on with a small signal, but stay on until zero power is passing through them, which normally happens 120 times a second with AC. Used in light dimmers, motor speed controls, and temperature control devices instead of relays.
