FDD3670
100V 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.
• 34 A, 100 V. RDS(ON) = 32 mΩ @ V GS = 10 V
RDS(ON) = 35 mΩ @ V GS = 6 V
• Low gate charge (57 nC typical)
These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable
RDS(ON) specifications.
• Fast switching speed
• High performance trench technology for extremely
low RDS(ON)
The result is a MOSFET that is easy and safer to drive
(even at very high frequencies), and DC/DC power
supply designs with higher overall efficiency.
• High power and current handling capability

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.
a) RθJA= 40oC/W when
mounted on a 1in2 pad of
2oz copper.
b) RθJA= 96oC/W on a
minimum mounting pad.
