A bidirectional rectifier (essentially two SCRs in parallel) that function as an electrically controlled switch for ac loads and having an npnpn structure that can be triggered into either forward or [..]

Generally the reverse of an SCR. The triac is similar to two reverse parallel SCRs, and can conduct in each direction. The main SCR circuit is anode to cathode and is controlled by a positive gate voltage. The triac conducts in both directions.

A three-terminal, gate controlled, bidirectional silicon switching device that can switch either alternating or direct currents.

An electronic device that provides switching action for either polarity of an applied voltage and can be controlled from a single gate. Usually composed of two SCR’s connected back to back.

A gated switching device which will conduct in either direction.

TRIode for Alternating Current. This is an electronic component approximately equivalent to two silicon-controlled rectifiers (SCRs/thyristors) joined in inverse parallel (paralleled but with the polarity reversed) and with their gates connected together. This results in a bidirectional electronic switch which can conduct current in either directio [..]

Provides similar functionality to a thyristor but supports bi-directional current flow.

A three-terminal device that is similar to two SCRs back to back with a common gate and common terminals. Although similar in construction and operation to the SCR, the triac controls and conducts cur [..]

A thyristor that can conductor in both directions. Because of this, it is useful for controlling alternating current. It is the equivalent of two SCRs in parallel with opposite polarities.
