AOB66918L-VB Product details
Back to previous pageProduct introduction：
** You are designing a high-power-density power module with limited PCB space, yet you need to handle up to 140A of output current and face severe thermal challenges. Ordinary MOSFETs either lack sufficient voltage tolerance or suffer from excessive conduction losses. The VBsemi AOB66918L-VB is designed for this exact scenario—it combines 100V voltage tolerance, 140A current capability, and an ultra-low 4mΩ on-resistance in a TO263 package, allowing high-power switching designs without compromise.**
