RJK0366DPA-WS#J0-VB Product details

Product introduction:

Are you designing a high-power-density DC-DC converter or battery management system with limited PCB space but needing to handle currents up to 80A? Ordinary MOSFETs either have large packages or suffer from high conduction losses. The VBsemi RJK0366DPA-WS#J0-VB is designed for this—it uses a small DFN8(5X6) surface-mount package, combining 30V drain-source voltage, 80A current capability, and an ultra-low on-resistance of 7mΩ, so high-current power designs no longer worry about heat dissipation and space.
