MSQ7434N
Dual N-Channel 30-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
SOIC-8PP
are DC-DC converters and power management in portable and
battery-powered products such as computers, printers,
PCMCIA cards, cellular and cordless telephones.
Key Features:
• 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
