FDR4420A
Single N-Channel, Logic Level, PowerTrenchTM MOSFET
General Description
Features
The SuperSOT-8 family of N-Channel Logic Level MOSFETs
have been designed to provide a low profile, small footprint
alternative to industry standard SO-8 little foot type product.
11 A, 30 V. RDS(ON) = 0.009 Ω @ VGS = 10 V,
RDS(ON) = 0.013 Ω @ VGS = 4.5 V.
These MOSFETs are produced using Fairchild Semiconductor's
advanced PowerTrench process that has been tailored to
minimize the on-state resistance and yet maintain superior
switching performance.
Fast switching speed.
These devices are well suited for low voltage and battery
powered applications where small package size is required
without compromising power handling and fast switching.

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RθJC is guaranteed by design
while RθCA is determined by the user's board design. RθJA shown below for single device operation on FR-4 board in still air.
