40V N-Channel PowerTrench® MOSFET
General Description
Features
These N-Channel MOSFETs are produced using
Fairchild Semiconductor’s advanced PowerTrench
process that has been especially tailored to minimize
on-state resistance and yet maintain superior switching
performance.

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)
50°C/W when mounted
on a 1in2 pad of 2 oz
copper
b) 125°C/W when mounted on a
minimum pad.
Scale 1 : 1 on letter size paper
2 Test: Pulse Width < 300μs, Duty Cycle < 2.0%
3. BV(avalanche) Single-Pulse rating is guaranteed if device is operated within the UIS SOA boundary of the device.
