Fairchild Releases P-Channel MOSFET In CSP That Offers 0.4mm Profile

November 06, 2008 by Jeff Shepard

Fairchild Semiconductor announced 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 state-of-the art WL-CSP packaging to minimize both RDS (ON) and required PCB space.

This P-Channel MOSFET is said to offer 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) (74mΩ typical @ -4.5V VGS), it is said to reduce conduction losses and to provide excellent power dissipation (1.9W).

The FDZ391P expands Fairchild’s offering of portable design solutions that are integral in conserving space and extending battery life. The company states that these products bring designers significant reduction in form factor along with excellent thermal and electrical performance to address the requirements of portable applications. These solutions 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 utilizes 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.

The units are priced (each, 1000 pcs.) at US$0.55 with a delivery of 12-14 weeks.
