FDD9409L-F085 Description

Short technical summary and product information.

The FDD9409L-F085 is an N-Channel Logic Level PowerTrench MOSFET from onsemi. It is designed for 40V drain-source voltage and supports continuous drain current up to 90A at 25°C case temperature. The device features a very low typical on-resistance of 2.1mΩ at VGS=10V and ID=80A, with a maximum of 2.6mΩ. It also offers a logic-level gate drive with threshold voltage ranging from 1.0V to 3.0V.

 

Key electrical characteristics include a total gate charge of 52nC typical, input capacitance of 3360pF, and single pulse avalanche energy rating of 33.7mJ. The junction-to-case thermal resistance is 1°C/W, and the operating temperature range is -55°C to 175°C. The device is qualified to AEC Q101 and is RoHS compliant.

 

The FDD9409L-F085 is housed in a standard TO-252 (DPAK) surface-mount package with gull-wing leads. It is suitable for automotive applications such as engine control, powertrain management, solenoid and motor drivers, electronic steering, and 12V system power switches. Please note that this device is discontinued and not recommended for new designs.
