Freescale AO48 40/ MC48 40 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. • • • • PRODUCT SUMMARY VDS (V) rDS(on) m(Ω) 22 @ VGS = 10V 40 27 @ VGS = 4.5V 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 ID (A) 8.3 7.3 1 8 2 7 3 6 4 5 ABSOLUTE MAXIMUM RATINGS (TA = 25 oC UNLESS OTHERWISE NOTED) Parameter Symbol Limit Units VDS 40 Drain-Source Voltage V VGS ±20 Gate-Source Voltage o TA=25 C a Continuous Drain Current Pulsed Drain Current o 8.3 ID TA=70 C b Continuous Source Current (Diode Conduction) a IDM ±50 IS 2.3 o TA=25 C a Power Dissipation o Operating Junction and Storage Temperature Range Maximum Junction-to-Ambient a t <= 10 sec Steady-State RθJA W 1.3 TJ, Tstg Symbol A 2.1 PD TA=70 C THERMAL RESISTANCE RATINGS Parameter A 6.8 o -55 to 150 Maximum C Units 62.5 o 110 o C/W C/W Notes a.
