IXFN280N085 Description

Short technical summary and product information.

The IXFN280N085 is an N-Channel power MOSFET manufactured by IXYS. It is designed for high-current switching applications with a drain-source voltage rating of 85V and a continuous drain current of 280A at case temperature. The device utilizes MOSFET (Metal Oxide) technology.

Key electrical characteristics include a maximum drain-source on-resistance of 4.4mOhm at 100A and 10V gate drive, a maximum gate threshold voltage of 4V at 8mA, and a maximum gate charge of 580nC at 10V. Input capacitance is 19000pF at 25V. The device can dissipate up to 700W at case temperature.

The MOSFET is housed in a SOT-227-4 (miniBLOC) package with chassis mount configuration, suitable for direct mounting to a heatsink. The operating junction temperature range is -55°C to 150°C. The gate-source voltage rating is ±20V.

This component is suitable for applications requiring high current handling and low conduction losses, such as power supplies, motor drives, and inverters. The SOT-227B package provides robust thermal performance.
