TK380A65Y,S4X-VB Product details
Back to previous pageProduct introduction：
You are designing a high-efficiency switching power supply that needs to withstand 650V high voltage while controlling losses and temperature rise. Ordinary high-voltage MOS tubes either have high on-resistance or insufficient avalanche capability. VBsemi TK380A65Y,S4X-VB is designed for this—it is based on SJ_Multi-EPI superjunction technology, achieving a balanced combination of 650V withstand voltage, 9A continuous current, and 550mΩ on-resistance in a TO220F package, allowing high-voltage power supply designs to find an ideal balance between reliability and efficiency.
