SPN8439-N-Channel Enhancement Mode MOSFET


SPN8439-N-Channel Enhancement Mode MOSFET DataSheet

DESCRIPTION
The SPN8439 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.

FEATURES 
􀂋 30V/6.2A,RDS(ON)= 42mΩ@VGS=4.5V
􀂋 30V/5.4A,RDS(ON)= 54mΩ@VGS=2.5V
􀂋 Super high density cell design for extremely low RDS (ON)
􀂋 Exceptional on-resistance and maximum DC current capability
􀂋 SOT-223 package design

APPLICATIONS
􀁺 Power Management in Note book
􀁺 DC/DC Converter
􀁺 LCD Display inverter

( SOT-223 )
