description AMS8205A is the dual n-channel enhancement mode power field effect transistor which is produced using high cell density, dmos trench technology. this high density process is especially tailored to minimize on-state resistance. these devices are particularly suited for low voltage application, such as notebook computer power management and other battery powered circuits, where high-s ide switching is required. pin configuration tssop-8 s subcontractor y: year a: week code ordering information part number package part marking AMS8205A tssop-8 sya week code code : a ~ z(1~26) ; a ~ z(27~52) AMS8205A st8 : tssop-8; r: tape reel ; g: pb ? free feature z 20v/6.0a, r ds(on) = 30m-ohm@v gs =4.5v z 20v/5.0a, r ds(on) =42m-ohm@v gs =2.5v z super high density cell design for extremely low r ds(on) z exceptional low on-resistance and maximum dc current capability z tssop-8 package design AMS8205A sya d2 s2 s2 g2 8 7 6 5 1 2 3 4 d1 s1 s1 g1
