Analog Power Freescale AM2322N AO3406/ MC3406 N-Channel 30-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 SOT-23 saves board space • Fast switching speed • High performance trench technology PRODUCT SUMMARY VDS (V) rDS (on ) (Ω) 0.085 @ VGS = 10V 30 0.125 @ VGS = 4.5V ID (A) 2.5 1.7 G D S o ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Maximum Units Drain-Source Voltage VDS 30 V Gate-Source Voltage ±20 VGS o TA=25 C a Continuous Drain Current Pulsed Drain Current o TA=70 C b 2.5 ID IDM a 10 IS Continuous Source Current (Diode Conduction) TA=25 C a o TA=70 C 1.25 PD THERMAL RESISTANCE RATINGS Parame te r t <= 5 sec a Maximum Junction-to-Ambient Steady-State Symbol R THJA W 0.8 TJ, Tstg Operating Junction and Storage Temperature Range A 0.46 o Power Dissipation A 2 o C -55 to 150 Maximum 150 200 Units o C/W Notes a.
