FDH44N50 MOSFETs by ON Semiconductor

Power MOSFET, N-Channel, UniFETTM, 500 V, 44 A, 120 mΩ, TO-247


UniFETTM MOSFET is a high voltage MOSFET family based on planar stripe and DMOS technology. This MOSFET is tailored to reduce on-state resistance, and to provide better switching performance and higher avalanche energy strength. 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.
