N-Channel 30-V (D-S) MOSFET
These miniature surface mount MOSFETs utilize a
high cell density trench process to provide low
r_DS(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 r_DS(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
