TK55S10N1,LQ-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a high-power DC-DC converter with an input bus voltage up to 100V and a load current approaching 100A. Ordinary MOS tubes either lack sufficient voltage tolerance or have high conduction losses that overwhelm the heatsink. The VBsemi TK55S10N1,LQ-VB is designed for this—it integrates 100V withstand voltage, 100A current carrying capacity, and an on-resistance of only 5mΩ into the compact TO252 package, allowing high-power power supply designs to compromise neither performance nor space.
