Alpha & Omega Semiconductor Inc. AO4821 is a dual P-Channel MOSFET array designed for high-efficiency switching applications. This component features a Drain-Source Voltage (Vdss) of 12V and a continuous Drain Current (Id) of 9A at 25°C. The AO4821 offers a low On-Resistance (Rds On) of 19mOhm at 9A and 4.5V, crucial for minimizing power loss. Its logic level gate feature enhances compatibility with a wider range of control signals. The device is packaged in an 8-SOIC (0.154", 3.90mm Width) format, suitable for surface mounting and supplied on tape and reel. With a maximum power dissipation of 2W and an operating temperature range of -55°C to 150°C (TJ), this MOSFET array is ideal for use in consumer electronics, power management, and portable device designs. Key electrical characteristics include a Gate Charge (Qg) of 23nC @ 4.5V and Input Capacitance (Ciss) of 2100pF @ 6V.
