2SK3305-S-AZ-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-voltage switching power supply or inverter where the input bus voltage reaches hundreds of volts, while also considering heat dissipation and reliability? Standard low-voltage MOSFETs lack sufficient voltage rating, while high-voltage MOSFETs often have high conduction losses. VBsemi 2SK3305-S-AZ-VB is designed for this purpose—it combines 650V drain-source voltage, 7A continuous drain current capability, and 1300mΩ on-resistance in a TO262 package, making the power stage design of high-voltage systems more reliable and manageable.
