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.
Logic-level gate Thyristors belong to our STPOWER family.
