TK3A90E,S4X-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-voltage auxiliary power supply or industrial control module that requires a switching transistor capable of withstanding a 950V bus voltage while delivering a stable 3A current? Ordinary high-voltage MOSFETs often suffer from high voltage drop and thermal losses. The VBsemi TK3A90E,S4X-VB is built for such scenarios—it features a To220F fully molded package, a single N-channel planar gate structure, covering high-voltage applications with 950V withstand voltage and 3A current capability, while leveraging optimized conduction characteristics to make high-voltage switching design more reliable and worry-free.
