P-Channel Enhancement Mode Field Effect Transistor
General Description
Features
These P-Channel enhancement mode field effect
transistors are produced using Fairchild’s proprietary,
high cell density, DMOS technology. This very high
density process has been designed to minimize onstate resistance, provide rugged and reliable
performance and fast switching. They can be used, with
a minimum of effort, in most applications requiring up to
0.13A DC and can deliver current up to 0.52A.
This product is particularly suited to low voltage
applications requiring a low current high side switch.

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.
