RJK0851DPB-00#J5-VB Product details
Back to previous pageProduct introduction：
VBsemi RJK0851DPB-00#J5-VB is a Single N-channel field-effect transistor using Trench technology, designed for medium and low voltage high-current power conversion and high power density control scenarios. Its LFPAK56 package offers excellent heat dissipation and low parasitic parameters, suitable for high-current PCB layouts and compact power systems. The device provides stable switching characteristics within an 80V drain-source voltage range, with on-resistance as low as 6mΩ at 10V gate drive, effectively reducing conduction losses; it also supports 4.5V logic drive for easy direct connection with modern control chips.
