Dual N- and P-Channel Enhancement Mode Field Effect Transistor
General Description
These dual N- and P-Channel enhancement mode power field effect transistors are produced using Fairchild's propretary, high cell density, DMOS technology. This very high density process is especially tailored to minimize on-state resistance and provide superior switching performance. These devices are particularly suited for low voltage applications such as notebook computer power management and other battery powered circuits where fast switching, low in-line power loss, and resistance to transients are needed.
Features
N-Channel 3.9A, 30V.RDS(ON) = 0.065 @VGS = 10V RDS(ON) = 0.095 @VGS = 4.5V. P-Channel -3.5A,-30V.RDS(ON)= 0.085 @VGS = -10V RDS(ON)= 0.190 @VGS = -4.5V.

High density cell design for extremely low RDS(ON).
High power and current handling capability in a widely used surface mount package. Dual (N & P-Channel) MOSFET in surface mount package.

Notes: 1. RJA is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RJC is guaranteed by design while RCA is determined by the user's board design.
