Single N-Channel Logic Level PowerTrench MOSFET
General Description
This N-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.
This device is well suited for low voltage and battery
powered applications where low in-line power loss and
fast switching are required.
Applications
Battery switch
Load switch
Motor controls
January 2000
Features
12.5 A, 30 V. RDS(ON) = 0.009 W @ VGS = 10 V
RDS(ON) = 0.013 W @ VGS = 4.5 V
Low gate charge.
Fast switching speed.
High performance trench technology for extremely
low RDS(ON).
High power and current handling capability.

Notes:
1: RqJA 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. RqJC is guaranteed by design while RqCA is determined by the user's board design.
Scale 1 : 1 on letter size paper
2: Pulse Test: Pulse Width £ 300 ms, Duty Cycle £ 2.0%
