2SK1808-E-VB Product details
Back to previous pageProduct introduction：
Are you designing an industrial-grade switching power supply or photovoltaic inverter, with a high-voltage bus up to 800V or even higher, and need to handle surges and voltage spikes? Ordinary MOSFETs either lack sufficient voltage tolerance or have excessive conduction losses, making it difficult to balance system stability and efficiency. The VBsemi 2SK1808-E-VB is designed for this purpose—it integrates a 950V withstand voltage, 6A continuous drain current, and a low on-resistance of 2400mΩ in a TO220F fully insulated package, providing a solid foundation for high-voltage, high-reliability applications.
