| Thyristors are "normally-off" switches that can be triggered "on" by a small current pulse into the gate electrode. Once turned on (or "triggered"), the component then stays in the conducting state even when the gate on-signal is removed. It only returns to the "off" (blocking) state if the current falls below a certain minimum or if the direction of the current is reversed.

Thyristors are typically used as phase-controlled current valves for AC to DC conversion and vice versa, operating at low frequencies (most often around AC line frequency). In the conducting state, thyristors feature very low losses, making them attractive devices to efficiently control very high currents and energies.
All ABB Thyristors are press-pack devices. They are pressed with a relatively high force onto heat-sinks which also serve as electrical contacts to the thyristor terminals.
