FDMS8848NZ
N-Channel PowerTrench^® MOSFET
40 V, 49 A, 3.1 mΩ
Features
General Description
„ Max r_DS(on) = 3.1 mΩ at V_GS = 10 V, I_D = 22.8 A
„ Max r_DS(on) = 5.1 mΩ at V_GS = 4.5 V, I_D = 17.5 A
„ Advanced Package and Silicon combination for low r_DS(on)
and high efficiency
„ MSL1 robust package design
„ RoHS Compliant
The FDMS8848NZ has been designed to minimize losses in
power conversion application. Advancements in both silicon and
package technologies have been combined to offer the lowest
r_DS(on) while maintaining excellent switching performance.
Applications
„ Computing VR & IMVP Vcore
„ Secondary Side Synchronous Rectifier
„ POL DC/DC Converter
„ Oring FET/ Load Switching
