The AUIRFB8409 is an N-Channel enhancement mode power MOSFET from Infineon's HEXFET family, designed for automotive and high-current applications. It features a drain-source voltage rating of 40V and a continuous drain current of 195A (package limited at 25°C). The device achieves an ultra-low maximum on-resistance of 1.3mΩ at 10V gate drive, with a typical value of 0.97mΩ.
This MOSFET supports a maximum junction temperature of 175°C and offers fast switching performance with a maximum gate charge of 450nC at 10V. The input capacitance is rated at 14240pF at 25V drain-source. It is capable of repetitive avalanche operation up to the maximum junction temperature, with a single pulse avalanche energy rating of 760mJ (thermally limited) and a tested value of 1360mJ.
The device is housed in a through-hole TO-220-3 package (TO-220AB) and is lead-free and RoHS compliant. It is suitable for applications such as electric power steering, battery switches, start/stop micro-hybrid systems, heavy loads, and DC-DC converters.
The maximum drain-source voltage (Vdss) is 40V.
The continuous drain current is 195A (package limited at 25°C) and 409A (silicon limited at 25°C).
