(v gs = -10v) r ds(on) < 200m ? (v gs = -4.5v) r ds(on) < 280m ? (v gs = -2.5v) the AO7405 uses advanced trench technology to provide excellent r ds(on) , low gate charge, and operation with gate voltages as low as 2.5v, in the small sot363 footprint. it can be used for a wide variety of applications, including load switching, low current inverters and low current dc-dc converters. standard product AO7405 is pb-free (meets rohs & sony 259 specifications). AO7405l is a green product ordering option. AO7405 and AO7405l are electrically identical. g d s sc-70-6 (sot-363) top view s g d d d d p-channel enhancement mode field general description effect transistor www.freescale.net.cn 1 / 4
