Fairchild has set an important precedent in MOSFET technology through the FDH series.  This cost-effective technology enhances system performance in the areas of both efficiency and reliability.  Renown for it’s fast switching speed, this MOSFET series provides an excellent solution in both high-power and high-current applications, all the while optimizing switching performance.   

The ruggedness that this technology offers, combined with its low package cost, has made the MOSFET universally preferred for all commercial-industrial applications.   The robust design is ideal for applications that require large amounts of power. 

By delivering superior performance, in its MOSFET series, backed by higher efficiency, lower conduction losses and greater power density, Fairchild offers unique technological solutions ideal for power supplies, mobile, lighting, motor computing, consumer and automotive applications.  Innovation continues to be at the forefront of Fairchild’s state of the art technology, providing global energy-efficient solutions.

Perfect for commercial, automotive and industrial applications, the FDH44N50 (this part is lead free) has the capacity to operate at 500V within an operating temperature range of 175 degrees C.  The net result translates to a lower resistance (RDS (on) = 0.12 mOhms). 

Repetitively avalanche rated, the FDH44N50 is able to reduce power dissipation levels to approximately 750 watts. The FDH44N50 provides high speed, robust efficiency combined with low on-resistance and cost-effectiveness all in a TO-247 package format.
