The FDT439N, produced by ON Semiconductor, is an N-Channel enhancement mode power field effect transistor (MOSFET). It is built using ON Semiconductor's proprietary, high cell density, DMOS technology. This advanced technology allows the FDT439N to have a very high density process, which is tailored to minimize on-state resistance and provide superior switching performance. The device is capable of handling 6.3A at 30V and exhibits low on-state resistance (RDS(on)) of 0.045 at VGS = 4.5V and 0.058 at VGS = 2.5V, indicating efficient operation.
