RJK1055DPB-00#J5-VB Product details
Back to previous pageProduct introduction：
Product Description
Imagine this: you are designing a high-power-density industrial power module with an input bus voltage up to 100V, yet the switching transistor is required to continuously output nearly 70A current under limited heat dissipation conditions. Ordinary MOSFETs either have insufficient withstand voltage or suffer from high conduction loss that makes them hot. VBsemi RJK1055DPB-00#J5-VB is born for this—it packs 100V withstand voltage, 69A current carrying capacity, and an on-resistance as low as 11.6mΩ into the compact LFPAK56 package, making high-voltage, high-current design no longer a headache for heat dissipation and space.
