Fairchild FDU6644 30v n-channel powertrench mosfet Datasheet

FDD6644/FDU6644
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 gate charge, low RDS(ON) and fast switching speed.
• 67 A, 30 V.
RDS(ON) = 8.5 mΩ @ VGS = 10 V
RDS(ON) = 10.5 mΩ @ VGS = 4.5 V
• High performance trench technology for extremely
low RDS(ON)
Applications
• Low gate charge (25 nC typical)
• DC/DC converter
• 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 = 40°C/W when mounted on a
1in2 pad of 2 oz copper
b) RθJA = 96°C/W when mounted
on a minimum pad.
Scale 1 : 1 on letter size paper
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%
3. Maximum current is calculated as:
PD
R DS(ON)
where PD is maximum power dissipation at TC = 25°C and RDS(on) is at TJ(max) and VGS = 10V. Package current limitation is 21A
