A diverse range of SCRs, DIACs, and TRIACs for electronic projects. SCRs (Silicon Controlled Rectifiers) are semiconductor devices that act as electrically controlled switches. SCRs are members of the semiconductor family, which also includes transistors and diodes. An SCR’s primary function is to act as a switch that can turn on or off small or large amounts of power. This function occurs without the need for mechanical components. Check out our extensive list to find what you’re looking for.
