FDC6327C

Dual N & P-Channel 2.5V Specified PowerTrenchTM MOSFET

FDC6327C

July 2000

General Description

These N & P-Channel 2.5V specified MOSFETs are produced using Fairchild Semiconductor's advanced PowerTrench process that has been especially tailored to minimize on-state resistance and yet maintain low gate charge for superior switching performance.

These devices have been designed to offer exceptional power dissipation in a very small footprint for applications where the bigger more expensive SO-8 and TSSOP-8 packages are impractical.

Applications

• DC/DC converter

• Load switch

• Motor driving
