Fairchild Semiconductor – P-Channel MOSFET Offers Low RDS(ON) in a 1mm x 1.5mm WL-CSP Package

Fairchild Semiconductor brings designers of smart phones, cell phones, netbooks, medical and other portable applications a single P-Channel MOSFET that enables higher levels of efficiency and a small form factor. The FDZ197PZ offers an RDS(ON) value of 64mOhm at VGS= -4.5V, 15 percent less than alternate solutions. This feature increases efficiency and offers a 1mm x 1.5 mm footprint, reducing board space requirements. Its WL-CSP package provides excellent power dissipation and conduction losses characteristics compared to conventional plastic-packaged MOSFETs in a similar footprint. Unlike other MOSFETs in its class, the FDZ197PZ offers robust ESD capability (4kV), protecting the device from stresses caused by ESD events that could potentially disable the application.
