TK4P60D,RQ-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing an industrial switching power supply or AC-DC converter module, facing a 600V high-voltage bus. You need to ensure stability and reliability while achieving efficient heat dissipation in a limited space. Ordinary MOS transistors either have insufficient voltage tolerance or excessive conduction loss. VBsemi TK4P60D, RQ-VB is designed for this—it uses mature planar technology, integrating 600V withstand voltage, 4A continuous drain current, and a low on-resistance of 1440mΩ in a TO252 package, providing a solid and reliable switching core for high-voltage power conversion.
