MOSFET Transistors, ON Semi


ON Semi offers a substantial portfolio of MOSFET devices that includes high-voltage (>250V) and low-voltage (<250V) types. The advanced silicon technology provides smaller die sizes, which it is incorporated into multiple industry-standard and thermally-enhanced packages.
ON Semi MOSFETs provide superior design reliability from reduced voltage spikes and overshoot, to lower junction capacitance and reverse recovery charge, to elimination of additional external components to keep systems up and running longer.
