Alpha & Omega Semiconductor Inc. AO3498 is an N-Channel Power MOSFET designed for efficient switching applications. This device features a 30V drain-source voltage (Vdss) and a continuous drain current (Id) capability of 3.8A at 25°C. The AO3498 exhibits a maximum on-resistance (Rds On) of 55mOhms at 3.8A and 10V gate-source voltage. Key electrical parameters include a gate charge (Qg) of 20nC at 10V and an input capacitance (Ciss) of 235pF at 15V. The MOSFET operates with a threshold voltage (Vgs(th)) of 1.5V at 250µA and a maximum gate-source voltage (Vgs) of ±12V. With a maximum power dissipation of 1.4W at 25°C and an operating temperature range of -55°C to 150°C, the AO3498 is housed in a compact SOT-23-3 package, suitable for surface mounting. This component is commonly utilized in power management, consumer electronics, and industrial automation.
