WebSep 13, 2015 · 3. A MOSFET is turned on by applying voltage between the Gate and Source. In order to fully turn on, that voltage must be well above the MOSFET's 'threshold voltage' (Gate-Source voltage that just starts to turn it on). 'Logic Level' MOSFETs are fully turned on with ~4.5V, so they can be controlled by 5V CMOS logic. Web301 Moved Permanently. openresty los angeles to new zealand flights
