Si4466DY
Single N-Channel 2.5V Specified PowerTrench MOSFET
General Description
Features
This N-Channel 2.5V specified MOSFET is produced
using Fairchild Semiconductor's advanced
PowerTrench process that has been especially tailored
to minimize on-state resistance and yet maintain superior
switching performance.
•
•
Low gate charge (47nC typical).
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.
•
Fast switching speed.
•
High performance trench technology for extremely
low RDS(ON).
Applications
•
High power and current handling capability.
•
•
•
15 A, 20 V. RDS(on) = 0.0075 Ω @ VGS = 4.5 V
RDS(on) = 0.010 Ω @ VGS = 2.5 V.

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of the
drain pins. RθJC is guaranteed by design while RθJA is determined by the user's board design.
