description applications the spn1443 is the n-channel logic enhancement mode power field effect transistors are 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 cellular phone and notebook computer power management and other battery powered circuits, and low in-line power loss are needed in a very small outline surface mount package. z power management in note book z portable equipment z battery powered system z dc/dc converter z load switch z dsc z lcd display inverter features pin configuration ( sot-323 ; sc-70 ) part marking ? 30v/2.8a,r ds(on) = 65m ? @v gs =10v ? 30v/2.3a,r ds(on) = 90m ? @v gs =4.5v ? super high density cell design for extremely low r ds (on) ? exceptional on-resistance and maximum dc current capability ? sot-323 ( sc?70 ) package design 1 of 3 4008-318-123 sales@twtysemi.com http://www.twtysemi.com spn1443 smd type smd type smd type smd type smd type smd type smd type smd type smd type smd type product specification
