Si4835DY
P-Channel Logic Level PowerTrench MOSFET
General Description
Features
This P-Channel Logic Level 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.
•
•
Extended VGSS range (±25V) for battery applications.
These devices are well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.
•
Low gate charge (19nC typical).
•
Fast switching speed.
•
High performance trench technology for extremely
low RDS(ON).
•
High power and current handling capability.
Applications
•
•
•
Battery protection

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.
