Freescale AO4924 / MC4924 N-Channel 30-V (D-S) MOSFET PRODUCT SUMMARY VDS (V) rDS(on) m(Ω) 32 @ VGS = 4.5V 30 40 @ VGS = 2.5V 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 SOIC-8 saves board space Fast switching speed High performance trench technology ID (A) 6.5 5.8 1 8 2 7 3 6 4 5 ABSOLUTE MAXIMUM RATINGS (TA = 25 oC UNLESS OTHERWISE NOTED) Parameter Symbol Limit VDS 30 Drain-Source Voltage VGS ±12 Gate-Source Voltage Continuous Drain Current Pulsed Drain Current TA=25oC a o TA=70 C b a Continuous Source Current (Diode Conduction) TA=25 C TA=70oC ±50 IS 2.3 Maximum Junction-to-Ambient a Symbol t <= 10 sec Steady-State RθJA A 2.0 PD W 1.3 TJ, Tstg THERMAL RESISTANCE RATINGS Parameter A ±5.3 IDM Operating Junction and Storage Temperature Range V 6.5 ID o Power Dissipationa Units o C -55 to 150 Maximum Units 62.5 o 110 o C/W C/W Notes a.
