| AOL1442 N-Channel Enhancement Mode Field Effect Transistor General Description The AOL1442 uses advanced trench technology and design to provide excellent R DS(ON) with low gate charge. This device is suitable for use in PWM, load switching and general purpose applications. Standard Product AOL1442 is Pb-free (meets ROHS & Sony 259 specifications). AOL1442L is a Green Product ordering option. AOL1442 and AOL1442L are electrically identical. Features VDS (V) = 30V (V GS = 10V) ID = 75A RDS(ON) < 5m (VGS = 10V) RDS(ON) < 9m (VGS = 4.5V) UIS Tested Rg,Ciss,Coss,Crss Tested Ultra SO-8TM Top View D Fits SOIC8 footprint !

Copper, in a still air environment with T A =25C. The Power dissipation P DSM is based on R JA and the maximum allowed junction temperature of 150C. The value in any given application depends on the user's specific board design, and the maximum temperature of 175C may be used if the PCB allows it. B. The power dissipation P D is based on T J(MAX)=175C, using junction-to-case thermal resistance, and is more useful in setting the upper dissipation limit for cases where additional heatsinking is used. C: Repetitive rating, pulse width limited by junction temperature T J(MAX)=175C. D. The R JA is the sum of the thermal impedence from junction to case R JC and case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300 s pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T J(MAX)=175C. G.The maximum current rating is limited by bond-wires. H. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25C. The SOA curve provides a single pulse rating. I. Revision 0: Mar 2006 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
