December 2006
FDD8750 N-Channel PowerTrench(R) MOSFET
25V, 2.7A, 40m Features General Description
This N-Channel MOSFET has been designed specifically to improve the overall effciency 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. Max rDS(on) = 40m at VGS = 10V, ID = 2.7A Max rDS(on) = 60m at VGS = 4.5V, ID = 2.7A Low gate charge: Qg(10) = 6nC(Typ) Low gate resistance Avalanche rated and 100% tested RoHS Compliant

Notes: 1: RJA 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. RJC is guaranteed by design while RJA is determined by the user's board design. a. 40C/W when mounted on a 1 in2 pad of 2 oz copper; b. 96C/W when mounted on a minimum pad. 2: Pulse Test: Pulse Width < 300s, Duty cycle < 2.0%. 3: Starting TJ = 25C, L = 3mH, IAS = 3.6A, VDD = 25V, VGS = 10V.
