Ensuring immunity against voltage spikes is the main purpose feature of sensitive-gate SCRs, calculated for demanding applications such as GFI (ground fault interrupt) breakers.
ST successfully met the design challenge of keeping the necessary gate current to trigger under 100 µA, minimizing drive consumption. Our sensitive-gate SCRs can also withstand up to 1200 V with some limited overhead.
They are available from the tiny SMB-Flat package (X0115MUF and TS110-8) for GFI breakers up to the TO-220FP package for motorbike ignitions.
Logic-level gate Thyristors belong to our STPOWER family.

ST’s 8H Triacs have been designed for Industrial, Building, Residential, Appliances. Based on the new ST’s technology, the 8H Triacs are able to work at 800V & 150°C without compromise. It makes 8H Triacs the right choice to run in very hot confined electronic environment and improve the reliability of your system. Thanks to 8H Triacs robust dynamic turn-off commutation and high noise immunity at high temperature you can reduce your system size while increasing functional safety.
