| AOL1418 N-Channel Enhancement Mode Field Effect Transistor General Description The AOL1418 uses advanced trench technology to provide excellent R DS(ON), low gate chargeand low gate resistance. This device is ideally suited for use as a high side switch in CPU core power conversion. Standard Product AOL1418 is Pb-free (meets ROHS & Sony 259 specifications). AOL1418L is a Green Product ordering option. AOL1418 and AOL1418L are electrically identical.

B. The power dissipation PD is based on TJ(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 TJ(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 ms 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 TJ(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. Rev1: Dec 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
