Power MOSFETs for Battery or Load Switching

Fairchild Semiconductor provides designers of cellular handsets and other ultra-portable applications P-Channel PowerTrench® MOSFETs to meet their needs for a small sized battery or load switching solution with excellent thermal characteristics.

The FDMA905P and FDME905PT feature a MOSFET with low on-state resistance. These devices offer exceptional thermal performance for their physical size, and are also well suited to linear mode applications.


a. 2mm x 2mm MicroFET™ package offers low profile - 0.8mm maximum
b. Guaranteed MAX RDS(ON) = 16mΩ at VGS = -4.5V, ID = -10A)
c. Offers excellent thermal performance (RθJA = 52 °C/W)


a. 1.6mm x 1.6mm Thin MicroFET package offers ultra-low profile - 0.55mm max
b. Guaranteed MAX RDS(ON) = 22mΩ at VGS = -4.5V, ID = -8A)
c. Offers excellent thermal performance (RθJA = 60 °C/W)

The FDMA905P and FDME905PT are free from halogenated compounds and antimony oxides and are RoHS-compliant. Both devices provide safe operation at low voltage and are suitable for use in handsets and ultra-portable devices.
