FAIRCHILD FDN308P

FDN308P
P-Channel 2.5V Specified PowerTrench MOSFET
General Description
Features
This P-Channel 2.5V specified MOSFET uses a rugged
gate version of Fairchild’s advanced PowerTrench
process. It has been optimized for power management
applications with a wide range of gate drive voltage
(2.5V – 12V).
• –20 V, –1.5 A.
RDS(ON) = 125 mΩ @ VGS = –4.5 V
RDS(ON) = 190 mΩ @ VGS = –2.5 V
• Fast switching speed
• High performance trench technology for extremely
low RDS(ON)
Applications
• Power management
• SuperSOTTM -3 provides low RDS(ON) and 30% higher
power handling capability than SOT23 in the same
footprint
• Load switch
• Battery protection

Notes:
1.
RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
a) 250°C/W when mounted on a
0.02 in2 pad of 2 oz. copper.
b) 270°C/W when mounted on a
minimum pad.
