TK11A55D(STA4,Q,M)-VB Product details
Back to previous pageProduct introduction：
You are designing a highly reliable switching power supply or industrial drive circuit, and the high-voltage side requires a power MOS transistor that can withstand 650V and stably output 12A, while also considering heat dissipation and cost. Ordinary devices either have insufficient voltage tolerance or high conduction loss. VBsemi TK11A55D is designed for this purpose—it integrates 650V withstand voltage, 12A current capacity, and 680mΩ on-resistance in a TO220F fully isolated package based on mature planar technology, making high-voltage power supply design both safe and worry-free.
