FDMS9409-F085 Description

Short technical summary and product information.

FDMS9409-F085 is an N-channel power MOSFET from ON Semiconductor. This metal-oxide semiconductor device is rated for a drain-source voltage of 40V and a continuous drain current of 65A at case temperature 25°C. The maximum on-resistance is 3.2mOhm (typical 2.4mOhm) when driven with a 10V gate voltage at 65A drain current.

 

The MOSFET features a gate threshold voltage up to 4V at 250µA, a maximum total gate charge of 62nC at 10V, and an input capacitance of 3130pF at 20V drain-source voltage. It supports a maximum gate-source voltage of ±20V and dissipates up to 100W. The junction operating temperature range is -55°C to 175°C.

 

The device is supplied in a surface-mount 8-PowerVDFN package, also known as Power56 (supplier device package). This compact package is suited for high-current power switching and power management circuits. The product is listed as RoHS3 compliant.
