Complementary PowerTrench® MOSFET
Q1:30V,0.75A,0.4Ω; Q2:25V,0.41A,1.1Ω
Features
Q1: N-Channel
Max rDS(on) = 0.4Ω at VGS = 4.5V, ID = 0.75A
Max rDS(on) = 0.5Ω at VGS = 2.7V, ID = 0.67A
Q2: P-Channel
Max rDS(on) = 1.1Ω at VGS = –4.5V, ID = –0.41A
Max rDS(on) = 1.5Ω at VGS = –2.7V, ID = –0.25A
Very low level gate drive requirements allowing direct
operation in 3V circuits(VGS(th) <1.5V)
Very small package outline SC70-6
RoHS Compliant
General Description
These N & P-Channel logic level enhancement mode 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. This
device has been designed especially for low voltage applica-
tions as a replacement for bipolar digital transistors and small
signal MOSFETs. Since bias resistors are not required, this dual
digital FET can replace several different digital transistors, with
different bias resistor values.

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 RθJA is determined by the user's board design.
2. Pulse Test: Pulse Width < 300μs, Duty cycle < 2.0%.
a. 350°C/W when mounted on a
1 in2 pad of 2 oz copper . b. 415°C/W when mounted on a minimum pad
of 2 oz copper.
