FDS8840NZ Description

Short technical summary and product information.

The FDS8840NZ is an N-Channel PowerTrench MOSFET from On Semiconductor designed for low-loss power conversion. It features a drain-source breakdown voltage of 40V and a continuous drain current of 18.6A at 25°C. The device achieves a low on-resistance of 4.5mΩ at VGS=10V and 6.0mΩ at VGS=4.5V, enabling high efficiency in switching applications.

 

Key electrical characteristics include a typical gate charge of 144nC at VGS=10V and an input capacitance of 7535pF at VDS=20V. The MOSFET offers 6kV HBM ESD protection and a single pulse avalanche energy rating of 600mJ. It operates over a junction temperature range of -55°C to 150°C.

 

The device is housed in an 8-SOIC surface mount package (case code 751EB) and is supplied in tape and reel packaging with 2500 units per reel. It is Pb-Free, Halogen Free/BFR Free, and RoHS3 compliant. Typical applications include synchronous buck converters for Vcore and server power, notebook battery packs, and load switches.
