RJK1051DPB-00#J5-VB Product details
Back to previous pageProduct introduction：
**Product Introduction** Imagine this: You are designing a high-power-density DC-DC converter with an input bus voltage of up to 100V, requiring continuous output of tens of amperes, while controlling temperature rise and losses. Ordinary MOSFETs either lack sufficient voltage tolerance or have excessive on-resistance leading to heat dissipation challenges. The VBsemi RJK1051DPB-00#J5-VB is designed for this—it uses the advanced LFPAK56 package to integrate 100V voltage tolerance, 69A high-current capability, and an ultra-low on-resistance of 11.6mΩ, allowing high-voltage, high-power designs to confidently meet efficiency and reliability challenges.
