Fairchild Semiconductor addresses the low profile, electrical and thermal efficiency requirements of portable applications with its single P-Channel MOSFET in 1 x 1.5 x 0.4mm WL-CSP packaging.

The FDZ391P has been designed using Fairchild’s 1.5V rated PowerTrench process coupled with WL-CSP packaging to minimize both _{RDS (ON)} and required PCB space.

This P-Channel MOSFET offers a 40% lower profile than standard P-Channel MOSFETs accommodating the slim form factor requirements of next generation cell phones, MP3 players and other portable applications. With its low _{RDS (ON)} (74mOhm typical @ -4.5V V_GS), it reduces conduction losses and provides good power dissipation (1.9 Watts).
 
The FDZ391P expands Fairchild’s portable design products that conserve space and extend battery life. These products bring designers reduction in form factor along with high thermal and electrical performance to address the requirements of portable applications.

These systems include µSerDes serializer/deserializers, IntelliMAX advanced load switches, USB switches, DC-DC switches, logic translators and many other power management and signal conditioning technologies.
 
The FDZ391P uses lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
 
Samples available now, with delivery in 12 to 14 weeks, priced at US$0.55 each in 1000 pcs quantities.
