FDR6674A
30V N-Channel PowerTrench
MOSFET
General Description
Features
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
“low side” synchronous rectifier operation, providing an
extremely low R DS(ON) in a small package.
11.5 A, 30 V. R DS(ON) = 9.5 m
@ V GS = 4.5 V
R DS(ON) = 8.5 m
@ V GS = 10 V
High performance trench technology for extremely
low R DS(ON)
Applications
High power and current handling capability in a
smaller footprint than SO8
Synchronous rectifier
DC/DC converter

Notes:
1. R
JA 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. R
JC is guaranteed by design while R
CA is determined by the user's board design.
a) 70°/W when
mounted on a 1in 2

b) 125°/W when
mounted on a .04 in 2
pad of 2 oz copper
c) 135°/W when mounted on a
minimum pad.
