2SK3305B-S19-AY-VB Product details
Back to previous pageProduct introduction：
**Product Introduction** Imagine this: You are designing an industrial switching power supply or high-voltage auxiliary power supply with a bus voltage of up to 400V, requiring a switching tube that can withstand high voltage and stably output 5A current. Ordinary low-voltage MOS tubes cannot handle this, while high-voltage devices often have high on-resistance and complex drive requirements. VBsemi 2SK3305B-S19-AY-VB is designed for this—it uses a TO252 package, combining 500V voltage tolerance, 5A continuous drain current, and an on-resistance of 1040mΩ (10V drive) with the mature reliability of Planar technology, making high-voltage power supply design more composed and robust.
