MS48N40 N-Channel 40-V (D-S) MOSFET Description These miniature surface mount MOSFETs utilize a high cell density trench process to provide low RDS(on) and to ensure minimal power loss and heat dissipation. Typical applications are DC-DC converters and power management in portable and battery-powered products such as computers, printers, and PCMCIA cards, cellular and cordless telephones. Features • Low rDS(on) provides higher efficiency and extends battery life • Miniature SO-8 surface mount package saves board space • High power and current handling capability • Low side high current DC-DC Converter applications • RoHS compliant package Packing & Order Information 3,000/Reel Graphic symbol Publication Order Number: [MS48N40] © Bruckewell Technology Corporation Rev.
