Fairchild Semiconductor¡¯s MicroFET Power Switches in SC-75 Packaging Lower Thermal Resistance and RDS(ON) in Portable Applications

San Jose, California ­ November 6th, 2007 ­ Fairchild Semiconductor (NYSE: FCS) releases the FDMJ1023PZand the FDFMJ2P023ZMicroFET power switches for low power (<30V) applications such as charging, asynchronous DC/DC and load switching. These power switches operate with gate voltages as low as 1.5V while offering 75 percent lower R_DS(ON) and 66 percent lower thermal resistance compared to other solutions. Utilizing Fairchild¡¯s advanced PowerTrench® technology, the FDMJ1023PZ and FDFMJ2P023Z are housed in 2.0mm x 1.6mm SC-75 packaging, which is 65% smaller than 3 X 3mm SSOT-6 and 20% smaller than SC-70 packaging.

The advantage of these 2.0mm x 1.6mm MicroFET power switches is that they can deliver equivalent thermal and electrical performance of power switches packaged in 3mm X 3mm SSOT-6 packaging. Optimal performance in an ultra-compact package is pivotal for portable applications such as cell phones, digital cameras and games where more and more functions are packed into smaller and smaller PCB space. These applications can also benefit from their guaranteed operation down to 1.5V.

Key Features of the FDMJ1023PZand FDFMJ2P023Z:

• Space savings because these MicroFET power switches are 20 percent smaller than power switches in SC-70 packaging.
• Guaranteed operation down to 1.5V addressing the voltage needs of portable applications.
• Excellent electrical and thermal performance.
  • R_DS(ON)160mΩ @ VGS = -2.5V
  • Thermal resistance 89єC/W

Fairchild Semiconductor offers the industry¡¯s broadest portfolio of thermally enhanced ultra-compact, low-profile devices targeting low-power applications. These easy-to-implement, high-performance and space-saving MOSFETs are ideal for all of our customers¡¯ low-voltage switching and power management/battery charging systems.

The FDMJ1023PZand FDFMJ2P023Zutilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
