MOSFET N-CH 40V 240A D2PAK

Manufacturer: Infineon Technologies

Categories: Single FETs, MOSFETs

Quality Control: Learn More

Infineon Technologies HEXFET® AUIRFS8408-7P is an N-Channel MOSFET designed for high-power automotive applications. This component features a Drain-to-Source Voltage (Vdss) of 40V and a continuous drain current (Id) of 240A at 25°C (Tc), with a maximum power dissipation of 294W (Tc). The on-resistance (Rds On) is a low 1mOhm at 100A and 10V gate drive. Key parameters include a gate charge (Qg) of 315 nC at 10V and an input capacitance (Ciss) of 10250 pF at 25V. The device is housed in a PG-TO263-7-900 package, also known as TO-263-7, D2PAK, supporting surface mounting. It operates across an extended temperature range of -55°C to 175°C (TJ) and supports a maximum gate-to-source voltage (Vgs) of ±20V. This MOSFET is commonly utilized in electric vehicle powertrains, battery management systems, and other demanding automotive electronic systems.
