Class Information
Number: 327/469
Name: Miscellaneous active electrical nonlinear devices, circuits, and systems > Gating (i.e., switching input to output) > Utilizing three or more electrode solid-state device > Four or more layer device (e.g., thyristor, etc.) > Dc supply > Triac
Description: Subject matter including a bidirectional rectifier (essentially two SCRs in parallel) that functions as an electronically controlled switch and having an npnpn structure that can be triggered into either forward or reverse conduction by a pulse applied to its gate electrode.
