AM7442N Analog Power 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. • • • • PRODUCT SUMMARY VDS (V) rDS(on) m(Ω) 9 @ VGS = 10V 40 12 @ VGS = 4.5V ID (A) 20 17 SOIC-8PP Top View Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOIC-8PP saves board space Fast switching speed High performance trench technology S 1 S S G 2 3 4 D 8 7 6 5 D D D D G S N-Channel MOSFET o ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Limit Units VDS Drain-Source Voltage 40 V ±20 Gate-Source Voltage VGS o TA=25 C a Continuous Drain Current o ±20 ID TA=70 C b Pulsed Drain Current a Continuous Source Current (Diode Conduction) IDM ±50 IS 2.3 o TA=25 C a Power Dissipation o PD TA=70 C Operating Junction and Storage Temperature Range THERMAL RESISTANCE RATINGS Parameter a Maximum Junction-to-Ambient Steady State A 5.0 W 3.2 TJ, Tstg -55 to 150 Symbol t <= 10 sec A ±16 RθJA o C Maximum Units o 25 C/W 65 o C/W Notes a.
