Si4450DY
60V N-Channel PowerTrench^ MOSFET
General Description
This N-Channel 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.
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.
Applications
• DC/DC converter
• Load switch
• Motor drives
Features
• 8 A, 60 V. R_DS(on) = 0.020 Ω @ V_GS = 10 V
R_DS(on) = 0.025 Ω @ V_GS = 6 V.
• Low gate charge (30nC typical).
• Fast switching speed.
• High performance trench technology for extremely
low R_DS(ON).
• High power and current handling capability.
