FDS8690 N-Channel PowerTrench® MOSFET
January 2006
FDS8690 N-Channel PowerTrench® MOSFET
30V, 14A, 7.6mΩ General Description
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.
Features
Max rDS(on) = 7.6mΩ, VGS = 10V, ID = 14A Max rDS(on) = 11.4mΩ, VGS = 4.5V, ID = 11.5A High performance trench technology for extremely low rDS(on) and fast switching Very low gate charge High power and current handling capability 100% RG tested RoHS Compliant

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.

c) 125°C/W when mounted on a minimun pad
2. The diode connected between the gate and source serves only as protection against ESD. No gate overvoltage rating is implied. 3. Starting TJ = 25oC, L = 3mH, IAS = 11.8A , VDD = 24V, VGS = 10V.
