Alpha & Omega Semiconductor Inc. presents the AO4728, an N-Channel MOSFET from the SRFET™ series. This component features a 30V drain-to-source breakdown voltage and a continuous drain current capability of 20A (Tc). The low on-resistance of 4.3mOhm at 20A and 10V gate drive is facilitated by its Metal Oxide technology. Key parameters include a maximum gate charge (Qg) of 72 nC at 10V and an input capacitance (Ciss) of 4463 pF at 15V. The device integrates a Schottky diode within its body and is housed in an 8-SOIC package, suitable for surface mounting. Power dissipation is rated at 3.1W (Ta). The AO4728 is engineered for applications requiring efficient power switching, including consumer electronics and industrial automation.
