The Alpha & Omega Semiconductor Inc. AOI4146 is a single N-Channel MOSFET from the SDMOS™ series. This component features a 30V drain-to-source voltage (Vdss) and supports continuous drain currents of 15A at ambient temperature and 55A at case temperature. It offers a low on-resistance (Rds On) of 5.6mOhm maximum at 20A and 10V Vgs. The device is packaged in a TO-251A (IPAK) through-hole configuration, suitable for applications requiring robust power handling. Key parameters include a gate charge (Qg) of 42nC at 10V and input capacitance (Ciss) of 2440pF at 15V. Maximum power dissipation is rated at 2.5W (Ta) and 62W (Tc). The operating temperature range is -55°C to 175°C (TJ). This MOSFET is utilized in sectors such as industrial automation, power supplies, and automotive electronics.
