Single FETs, MOSFETs datasheet and documents for FDT3N40TF

FDT3N40TF

Single FETs, MOSFETs Overview

The onsemi FDT3N40TF is an N-channel enhancement mode MOSFET from the UniFET series, housed in a surface-mount SOT-223 package. It features a maximum drain-source voltage of 400 V and a continuous drain current of 2 A at case temperature. The device exhibits a typical on-resistance of 3.4 Ω at 10 V gate drive and handles up to 2 W of power dissipation. Key electrical limits include a gate-source voltage range of ±30 V, a minimum gate threshold voltage of 3 V, and a maximum junction temperature of +150 °C.
