Dual N-Channel 40-V (D-S) MOSFET
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, PCMCIA cards, cellular and cordless telephones. • • • • Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOIC-8 saves board space Fast switching speed High performance trench technology
