FDMC8651
N-Channel Power Trench® MOSFET
30 V, 20 A, 6.1 m
Features
General Description
„ Max rDS(on) = 6.1 mat VGS = 4.5 V, ID = 15 A
„ Max rDS(on) = 9.3 mat VGS = 2.5 V, ID = 12 A
„ Low Profile - 1 mm max in Power 33
„ 100% UIL Tested
„ RoHS Compliant
This device has been designed specifically to improve the
efficiency of DC/DC converters. Using new techniques in
MOSFET construction, the various components of gate charge
and capacitance have been optimized to reduce switching
losses. Low gate resistance and very low Miller charge enable
excellent performance with both adaptive and fixed dead time
gate drive circuits. Very low rDS(on) has been maintained to
provide a sub logic-level device.
Applications
„ Synchronous rectifier
„ 3.3 V input synchronous buck switch

NOTES:
1. RθJA is determined with the device mounted on a 1in2 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. 53 °C/W when mounted on a
1 in2 pad of 2 oz copper
b. 125 °C/W when mounted on
a minimum pad of 2 oz copper
2. Pulse Test: Pulse Width < 300 µs, Duty cycle < 2.0%.
3. Starting TJ = 25 °C; N-ch: L = 1 mH, IAS = 16 A, VDD = 27 V, VGS = 10 V.
