Freescale AO3414/MC3414 N-Channel 20-V (D-S) MOSFET / PRODUCT SUMMARY VDS (V) rDS(on) (Ω) 0.047 @ VGS = 4.5V 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. • • • • 20 ID (A) 4.3 0.055@ VGS = 2.5V 4.0 0.087@ VGS = 1.8V 3.2 G Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOT-23 saves board space Fast switching speed High performance trench technology D S o ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Ratings Units Drain-Source Voltage 20 VDS V VGS Gate-Source Voltage ±8 o TA=25 C a Continuous Drain Current o 4.3 ID TA=70 C b Pulsed Drain Current a Continuous Source Current (Diode Conduction) IDM 10 IS 1.6 o TA=25 C a Power Dissipation o Operating Junction and Storage Temperature Range a Maximum Junction-to-Ambient W 0.9 TJ, Tstg -55 to 150 Symbol M aximum t <= 5 sec Steady-State A 1.3 PD TA=70 C THERM AL RESISTANCE RATINGS Parameter A 3.6 R T HJA 100 166 o C Units o C/W Notes a.
