Single FETs, MOSFETs datasheet and documents for AON7421
Single FETs, MOSFETs Overview
The AON7421 is a 20V P-Channel MOSFET manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve low on-resistance and gate charge, making it suitable for load switch and battery protection applications. Key electrical parameters include a drain-source voltage (VDS) of 20V, a continuous drain current (ID) of 35A at VGS=10V, and a maximum on-resistance (RDS(ON)) of less than 2.8mΩ at VGS=10V and 3.6mΩ at VGS=4.5V. The device is tested for 100% unclamped inductive switching (UIS) and gate resistance.
