Web27 jan. 2024 · A TRIAC is a bidirectional, three-electrode AC switch that allows electrons to flow in either direction. It is the equivalent of two SCRs connected in a reverse-parallel arrangement with gates connected to each other. A TRIAC is triggered into conduction in both directions by a gate signal like that of an SCR. WebTRIAC (TRIode for Alternating Current) is a semiconductor device for controlling alternating current and as the name suggests it is a three terminal, four layer device but bidirectional in nature. Triacs are usually … Web25 jun. 2005 · A Triac is a semiconductor device - stands for TRIode AC switch - and is basically a bi-directional thyristor. It is a device that is normally off but will break down and conduct if a large enough voltage is applied in either direction and the breakdown current will "latch-on" and continue to flow until it falls below a chrome private browser
