2SK1313STR-E-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing an industrial switching power supply with a bus voltage of up to 400V, requiring a device to stably carry 5A current in a limited space while maintaining low losses. Ordinary high-voltage MOS tubes either lack sufficient voltage tolerance or have excessive on-resistance leading to thermal runaway. The VBsemi 2SK1313STR-E-VB is designed for this—it integrates 500V voltage tolerance, 5A current capacity, and a low on-resistance of 1040mΩ in a TO252 package, making high-voltage power supply design both reliable and efficient.
