FDS6990A
Dual N-Channel Logic Level PowerTrench® MOSFET
General Description
Features
These N-Channel Logic Level MOSFETs are produced
using
Fairchild
Semiconductor’s
advanced
PowerTrench process that has been especially tailored
to minimize the on-state resistance and yet maintain
superior switching performance.
• 7.5 A, 30 V.
RDS(ON) = 18 mΩ @ VGS = 10 V
RDS(ON) = 23 mΩ @ VGS = 4.5 V
• Fast switching speed
• Low gate charge
These devices are well suited for low voltage and
battery powered applications where low in-line power
loss and fast switching are required.
• High performance trench technology for extremely
low RDS(ON)
• High power and current handling capability
