March 1998 FDN338P P-Channel Logic Level Enhancement Mode Field Effect Transistor General Description Features TM SuperSOT -3 P-Channel logic level enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process is especially tailored to minimize on-state resistance. These devices are particularly suited for low voltage applications in notebook computers, portable phones, PCMCIA cards, and other battery powered circuits where fast switching, and low in-line power loss are needed in a very small outline surface mount package. SuperSOTTM-3 SuperSOTTM-8 SuperSOTTM-6 -1.6 A, -20 V, RDS(ON) = 0.13 Ω @ VGS = -4.5 V RDS(ON) = 0.18 Ω @ VGS = -2.5 V. Industry standard outline SOT-23 surface mount package using proprietary SuperSOTTM-3 design for superior thermal and electrical capabilities. High density cell design for extremely low RDS(ON). Exceptional on-resistance and maximum DC current capability.

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. Typical RθJA using the board layouts shown below on FR-4 PCB in a still air environment : a. 250oC/W when mounted on 0.02 in2 pad of 2oz Cu. a b. 270oC/W when mounted on a 0.001 in2 pad of 2oz Cu.
