FDH44N50 Datasheet PDF - Fairchild

●The FDH44N50 is a 500V N-channel Power MOSFET based on planar stripe and DMOS technology. This SMPS series MOSFET is tailored to reduce on-state resistance and to provide better switching performance and higher avalanche energy strength. The body diode"s reverse recovery performance of UniFET FRFET® MOSFET has been enhanced by lifetime control. Its trr is less than 100ns and the reverse dv/dt immunity is 15V/ns while normal planar MOSFETs have over 200ns and 4.5V/ns respectively. Therefore, it can remove additional component and improve system reliability in certain applications in which the performance of MOSFET"s body diode is significant. This device family is suitable for switching power converter applications such as power factor correction (PFC), flat panel display (FPD) TV power, ATX and electronic lamp ballasts. This product is general usage and suitable for many different applications.

● Low gate charge results in simple drive requirement

● Improved gate, avalanche and high reapplied dv/dt ruggedness

● Reduced miller capacitance and low input capacitance
