TK6A55DA(STA4,Q,M)-VB Product details
Back to previous pageProduct introduction：
You are designing a high-reliability switching power supply that needs to handle wide voltage input and complex load surges, but are troubled by the high on-resistance and difficult-to-control heat generation of high-voltage MOS tubes. VBsemi TK6A55DA is designed for this purpose—it integrates 650V withstand voltage, 10A current carrying capacity, and 830mΩ on-resistance into a TO220F fully plastic package, allowing high-voltage power supply design to find an ideal balance between safety and efficiency.
