AON6922

Overview

The AON6922 is a dual asymmetric N-channel MOSFET manufactured by Alpha & Omega Semiconductor Inc. under the aMOS™ series. It features a drain-source voltage (Vdss) of 30 V and a continuous drain current (Id) of 19 A at 25°C (case temperature). The device has a maximum gate-source voltage (Vgs) of ±20 V and a threshold voltage (Vgs(th)) of 2.2 V max at 250 µA. Key electrical parameters include a maximum gate charge (Qg) of 13 nC at 10 V, an input capacitance (Ciss) of 820 pF max at 15 V, and a maximum power dissipation of 3.1 W. It operates within a junction temperature range of -55°C to 150°C.
