IPA50R280E6-VB Product details
Back to previous pageProduct introduction：
IPA50R280E6-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. It adopts SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology to achieve an excellent balance between on-resistance and switching speed. The TO220F full-plastic package provides good insulation and heat dissipation capability, facilitating installation and creepage design. The combination of 500V withstand voltage, 18A current capacity, and 210mΩ on-resistance makes it a reliable choice for high-voltage applications such as server power supplies, charging station auxiliary power supplies, and industrial drives, especially suitable for projects with strict requirements for voltage margin and system stability.
