FDN028N20 Description

Short technical summary and product information.

The FDN028N20 is an N-Channel PowerTrench MOSFET manufactured by On Semiconductor using advanced trench technology to minimize on-state resistance while maintaining low gate charge for efficient switching. It is rated for a maximum drain-source voltage of 20V and a continuous drain current of 6.1A at 25°C ambient. The device features a typical on-resistance of 23mΩ and a maximum of 28mΩ at VGS=4.5V and ID=5.2A, with a typical gate threshold voltage of 0.9V. It is housed in a compact SUPERSOT-3 surface-mount package (SOT-23, 3-lead, 1.4x2.9mm case 527AG), making it suitable for space-constrained applications. The MOSFET is 100% UIL tested and is Pb-Free, Halide Free, and RoHS compliant. Typical applications include primary DC-DC converters and load switches.
