description AMS2301A is the pchannel logic enhancement mode power field effect transistor which is produced using high cell density, dmos trench techn ology.this high density process is especially tailored to minimize onstate resistance .these devices are particularly suited for low voltage application such as cellular phone and notebook computer power management, other battery powered circuits, and low inline po wer loss are required. the product is in a very small outline surface mount package. pin configuration sot-23 1.gate 2.source 3.drain part marking sot-23 y: year code a: process code feature - 20v/3.2a, r ds(on) =85m (typ.) @v gs = 4.5v 20v/2.0a, r ds(on) = 100m @v gs = 2.5v super high density cell design for extremely low r ds(on) exceptional onresistance and maximum dc current capability sot23 package design 3 1 2 d g s 3 1 2 s01ya
