Analog Power P-Channel 100-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 TSOP-6 saves board space Fast switching speed High performance trench technology AM3471P PRODUCT SUMMARY VDS (V) rDS(on) (Ω) 0.350 @ VGS = -10V -100 0.450 @ VGS = -4.5V ID (A) 2.0 1.8 1 2 3 6 5 4 ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Maximum Units Drai [ ... ]
