A semiconductor diode in which current through a third element, called the gate, controls turn-on, and the anode-to-cathode voltage controls turn-off.
A reverse blocking triode thyristor pnp device.
Also known as a thyristor; like a diode it only allows electric current to flow through it in one direction, but in addition it can be controlled so that its "turn-on" can be delayed indefinitely.
A solid state switch, sometimes referred to as a thyristor. The SCR has an anode, cathode and control rectification since it can be turned on at will. The SCR can rapidly switch large currents at high voltages. It is small sizes and low in weight.
Semi-conductor device which is small, efficient and operable at relatively high temperatures to convert AC current to DC current. The two ways it does this are, arranging the circuit so that both halves of the AC current flow in the same direction, which is called full-wave rectification or by suppressing the reverse direction of current flow, called half-wave rectification.
