TRIAC - Wikipedia
WEBA TRIAC (triode for alternating current; also bidirectional triode thyristor or bilateral triode thyristor) is a three-terminal electronic component that conducts current in either direction when triggered. The term TRIAC is a genericised trademark.

WEBMar 26, 2023 · A TRIAC is a three-terminal, five-layered, bidirectional power electronic switching device. It acts like two anti-parallel SCRs connected for bidirectional operation. It has three terminals: MT1, MT2, and gate. MT1 and MT2 are interchangeable.
An Introduction to TRIAC Basics - Technical Articles - EE Power
WEBJan 27, 2021 · 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.

What is TRIAC: Switching Circuit and Applications
WEBJul 20, 2018 · In this tutorial we will learn about the TRIAC, which is a bidirectional device meaning it can conduct in both the direction. Due to this property TRIAC is exclusively used where sinusoidal AC supply is involved.
TRIAC | Construction | Operation | Characteristics | Testing
WEBThe triac is a three-terminal bi-directional thyristor. It was developed as a device to control AC power. The triac replaces a pair of inverse parallel-connected SCRs. For low-to medium-current applications (up to about 100 A), the triac is less costly than two SCRs.
