The AON7292 from Alpha & Omega Semiconductor is a high-performance, 100V N-Channel MOSFET utilizing the latest Trench Power AlphaMOS (aMOS MV) technology. This component is optimized for fast-switching applications and features very low RDS(ON) values, with <24mΩ at VGS=10V and <32mΩ at VGS=4.5V, making it ideal for synchronous rectification in DC/DC and AC/DC converters, as well as isolated DC/DC converters in telecom and industrial applications. The AON7292 is housed in a compact DFN 3.3×3.3 package and complies with RoHS and Halogen-Free standards. Key specifications include a continuous drain current of 23A at Tc=25°C, a pulsed drain current of 45A, and a maximum power dissipation of 28W at Tc=25°C. The component also boasts low gate charge characteristics, with a total gate charge of 17nC at VGS=10V, ensuring efficient operation in high-speed switching environments. Additionally, it has been rigorously tested for Unclamped Inductive Switching (UIS) and gate resistance, ensuring reliability and performance in demanding applications.
