FDS8840NZ
N-Channel PowerTrench® MOSFET
April 2009
40 V, 18.6 A, 4.5 mΩ
Features
General Description
Max rDS(on) = 4.5 mΩ at VGS = 10 V, ID = 18.6 A
Max rDS(on) = 6.0 mΩ at VGS = 4.5 V, ID = 14.9 A
HBM ESD protection level of 6 kV typical(note 3)
High performance trench technology for extremely low rDS(on)
and fast switching
High power and current handling capability
Termination is Lead-free and RoHS Compliant
The FDS8840NZ has been designed to minimize losses in
power conversion application. Advancements in both silicon and
package technologies have been combined to offer the lowest
rDS(on) while maintaining excellent switching performance.

NOTES:
1. RθJA is determined with the device mounted on a 1 in2 pad 2 oz copper pad on a 1.5 x 1.5 in. board of FR-4 material. RθJC is guaranteed by design while RθCA is determined by
the user's board design.
a) 50 °C/W when mounted on a
1 in2 pad of 2 oz copper.
b) 125 °C/W when mounted on a
minimum pad.
2. Pulse Test: Pulse Width < 300 µs, Duty cycle < 2.0%.
3. The diode connected between the gate and source servers only as protection against ESD. No gate overvoltage rating is implied.
4. Starting TJ = 25 °C, L = 3 mH, IAS = 20 A, VDD = 40 V, VGS = 10 V.
