Fairchild is a leader in MOSFET technology for both power delivery and power conversion applications. We offer a substantial portfolio of MOSFET devices that includes high-voltage (>250V) and low-voltage (<250V) and multiple range of innovative packaging options as well as strong technical support. More OEMs choose Fairchild because we continue to provide leading edge MOSFET technologies for  AC-DC and DC-DC designs.

Our advanced silicon technology provides smaller die sizes, which we incorporate into multiple industry-standard and thermally-enhanced packages. This capability yields industry-leading power densities (amps delivered per cm2 board space) and superior thermal performance.

Our Featured MOSFETs Technologies Include:

Why Choose Our FETs

  • Power delivery solutions are part of Fairchild's core business, and we have continuously delivered leading power semiconductors for more than 50 years.
  • Combined MOSFET and gate driver IP to create application-optimized solutions that minimize both conversion and conduction losses associated with the overall system.
  • Ability to mix and match MOSFETs, controller and PWM driver IP with advanced processing and packaging capabilities to provide optimized component choices.
  • Our 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.
