| November 1997 FDC634P P-Channel Enhancement Mode Field Effect Transistor General Description These 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 such as cellular phone and notebook computer power management and other battery powered circuits where high-side switching, and low in-line power loss are needed in a very small outline surface mount package. Features -3.5 A, -20 V. RDS(ON) = 0.080 @ VGS = -4.5 V RDS(ON) = 0.110 @ VGS = -2.5 V. SuperSOTTM-6 package design using copper lead frame for superior thermal and electrical capabilities. High density cell design for extremely low RDS(ON). Exceptional on-resistance and maximum DC current capability.

RJA 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. RJC is guaranteed by design while RCA is determined by the user's board design. a. 78oC/W when mounted on a 1 in2 pad of 2oz Cu in FR-4 board. b. 156oC/W when mounted on a minimum pad of 2oz Cu in FR-4 board. 2.
