STL105N8F7AG-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power-density industrial power supply module where limited board space must handle switching currents of hundreds of amps? Traditional MOSFETs either have large packages or suffer from high conduction losses. The VBsemi STL105N8F7AG-VB is designed for this exact challenge – it integrates an 80V withstand voltage, 120A current carrying capability, and an ultra-low 4.5mΩ on-resistance into the compact DFN8(5X6) package, leveraging advanced SGT technology so high-power designs no longer compromise on heat dissipation and space.
