Web5 de jul. de 2016 · It does not hurt if we have too high hFE, because we want the transistor to saturate. But if the hFE is too low, the transistor will operate in forward active region, which limits the current of the load and generates a lot of heat. The reason to double the required hFE is that hFE varies drastically under different conditions. greenwood first presbyterian church
