NCE90N340F-VB Product details
Back to previous pageProduct introduction：
The NCE90N340F-VB is a Single N-MOS carefully optimized for high-voltage power switching scenarios. Using SJ_Multi-EPI superjunction technology, it achieves an excellent balance between on-resistance and switching speed. The TO220F fully molded package provides good insulation and thermal performance, facilitating installation and system layout. The combination of 900V withstand voltage, 20A current capacity, and 270mΩ on-resistance makes it a cost-effective choice for high-voltage applications such as industrial power supplies, photovoltaic inverters, and charging station auxiliary power supplies, especially for scenarios with strict requirements for reliability and temperature rise.
