Alpha & Omega Semiconductor Inc. presents the AOD421, a P-Channel MOSFET designed for efficient power switching applications. This component features a Drain-to-Source Voltage (Vdss) of 20 V and a continuous drain current (Id) of 12.5 A at 25°C. The device offers a low on-resistance (Rds On) of 75 mOhm maximum at 12.5 A and 10 V, with a gate drive voltage range of 2.5 V to 4.5 V. Key parameters include a maximum gate charge (Qg) of 4.6 nC at 4.5 V and input capacitance (Ciss) of 620 pF at 10 V. The AOD421 is housed in a TO-252 (DPAK) surface-mount package, allowing for robust thermal management with a maximum power dissipation of 2 W (ambient) and 18.8 W (case). This MOSFET is suitable for use in automotive and industrial systems requiring reliable power control. The operating junction temperature range is -55°C to 175°C.
