FDT439N June 1999 FDT439N N-Channel 2.5V Specified Enhancement Mode Field Effect Transistor General Description Features This N-Channel Enhancement mode field effect transistor 6.3 A, 30 V. RDS(on) = 0.045 @ VGS = 4.5 V is produced using Fairchild Semiconductor's proprietary, high cell density, DMOS technology. This very high RDS(on) = 0.058 @ VGS = 2.5 V density process is especially tailored to minimize on- state resistance, and provide superior switching Fast switching speed. performance. These products are well suited to low voltage, low current applications such as notebook High power and current handling capabitlity in a computer power management, battery powered widely used surface mount package. circuits, and DC motor control. Applications DC/DC converter Load switch Motor driving D D D D S S D G G SOT-223 * G S G D S SOT-223 (J23Z) Absolute Maximum Ratings TA = 25
