STK184N4F7AG-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or motor drive module with limited PCB space but needing to handle hundreds of amps of current? Ordinary MOSFETs either have high conduction losses or their packages cannot keep up with the heat dissipation. The VBsemi STK184N4F7AG-VB is designed for this – it packs a 40V withstand voltage, 150A current carrying capacity, and an on-resistance of only 0.7mΩ into the compact LFPAK56 SMD package, allowing high-current designs to stop compromising on heat and space.
