Alpha & Omega Semiconductor Inc. N-Channel Power MOSFET, part number AOB4184. This device features a 40V drain-source voltage (Vdss) and supports continuous drain current of 12A at ambient temperature (Ta) and 50A at case temperature (Tc). It offers a low on-resistance (Rds On) of 10mOhm maximum at 20A and 10V Vgs. The AOB4184 is designed for efficient power management with a maximum power dissipation of 2.5W (Ta) and 50W (Tc). Key electrical characteristics include a gate charge (Qg) of 35 nC maximum at 10V Vgs and input capacitance (Ciss) of 1800 pF maximum at 20V Vds. The MOSFET is housed in a TO-263-3, D2PAK package suitable for surface mounting and operates across a temperature range of -55°C to 175°C. This component finds application in power supply circuits and automotive systems. Supplied in Tape & Reel (TR) packaging.
