FDMS7656AS
N-Channel PowerTrench® SyncFET
30 V, 49 A, 1.8 mΩ
October 2014
Features
General Description
„ Max rDS(on) = 1.8 mΩ at VGS = 10 V, ID = 30 A
„ Max rDS(on) = 1.9 mΩ at VGS = 7 V, ID = 27 A
„ Advanced Package and Silicon combination for low rDS(on)
and high efficiency
„ SyncFET Schottky Body Diode
„ MSL1 robust package design
„ 100% UIL tested
„ RoHS Compliant
The FDMS7656AS 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. This
device has the added benefit of an efficient monolithic Schottky
body diode.
Applications
„ Synchronous Rectifier for DC/DC Converters
„ Notebook Vcore/ GPU low side switch
„ Networking Point of Load low side switch
„ Telecom secondary side rectification

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 of 2 oz copper.
2. Pulse Test: Pulse Width < 300 μs, Duty cycle < 2.0%.
3. EAS of 242 mJ is based on starting TJ = 25 °C, L = 1 mH, IAS = 22 A, VDD = 27 V, VGS = 10 V. 100% test at L = 0.3 mH, IAS = 34 A.
4. As an N-ch device, the negative Vgs rating is for low duty cycle pulse occurrence only. No continuous rating is implied.
