FDC6420C 20V N & P-Channel Power Trench MOSFETs General Description Features These N & P-Channel MOSFETs are produced using

• Q1 3.0 A, 20V. RDS(ON) = 70 mΩ @ VGS = 4.5 V

Fairchild Semiconductor’s advanced Power Trench

RDS(ON) = 95 mΩ @ VGS = 2.5 V

process that has been especially tailored to minimize on-state resistance and yet maintain superior

switching performance. • Q2 –2.2 A, 20V. RDS(ON) = 125 mΩ @ VGS = –4.5 V

RDS(ON) = 190 mΩ @ VGS = –2.5 V

These devices have been designed to offer exceptional power dissipation in a very small footprint

• Low gate charge

for applications where the bigger more expensive SO-8 and TSSOP-8 packages are impractical.

• High performance trench technology for extremely low RDS(ON).

Applications

• DC/DC converter • Super SOT –6 package: small footprint (72% smaller than • Load switch SO-8); low profile (1mm thick).

• LCD display inverter
