MOSFET Power, N-Channel, SMPS 500 V, 44 A, 120 m FDH44N50 Description UniFET MOSFET is ON Semiconductors high voltage www.onsemi.com MOSFET family based on planar stripe and DMOS technology. This MOSFET is tailored to reduce onstate resistance, and to provide better switching performance and higher avalanche energy strength. V R MAX I MAX DS DS(ON) D This device family is suitable for switching power converter 500 V 120 m 10 V 44 A applications such as power factor correction (PFC), flat panel display (FPD) TV power, ATX and electronic lamp ballasts. Features D Low Gate Charge Q Results in Simple Drive Requirement g (Typ. 90 nC) Improved Gate, Avalanche and High Reapplied dv/dt Ruggedness G Reduced R (110 m (Typ.) V = 10 V, I = 22 A) DS(on) GS D Reduced Miller Capacitance and Low Input Capacitance S (Typ. C = 40 pF) rss Improved Switching Speed with Low EMI 175C Rated Junction Temperature This Device is PbFree and is RoHS Compliant G Applications D S Lighting Uninterruptible Power Supply TO2473LD CASE 340CK ACDC Power Supply MARKING DIAGRAM Y&Z&3&K FDH44N50 Y = ON Semiconductor Logo &Z = Assembly Plant Code &3 = Numeric Date Code &K = Lot Code FDH44N50 = Specific Device Code ORDERING INFORMATION See detailed ordering and shipping information on page 2 of this data sheet.
