BUK9629-100B,118-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power DC-DC converter that needs to withstand the dual challenges of high voltage and high current, while also controlling temperature rise and losses. Ordinary MOSFETs either have insufficient voltage tolerance or high on-resistance, making thermal design difficult. The VBsemi BUK9629-100B,118-VB is designed for this—it combines 100V voltage tolerance, 70A current-carrying capability, and an on-resistance of only 20mΩ in a reliable TO263 (D2PAK) package, allowing high power density power systems to no longer compromise.
