TK1R4F04PB,LXGQ-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power motor driver or high-current DC-DC converter, and the PCB needs to balance current capacity, heat dissipation, and switching losses. Ordinary MOSFETs either have high on-resistance causing severe heating, or insufficient current rating requiring multiple parallel devices, increasing cost and board space. VBsemi TK1R4F04PB, LXGQ-VB is designed for this—it integrates 40V withstand voltage, 280A continuous current capability, and an ultra-low on-resistance of 1.4mΩ in a TO263 high-current package, making high-power power supply designs simpler, more efficient, and more reliable.
