R8019KNZ4C13-VB Product details
Back to previous pageProduct introduction：
The R8019KNZ4C13-VB is a Single N-MOSFET deeply optimized for high-voltage power switching scenarios, using SJ_Multi-EPI superjunction technology to achieve a balance between low on-resistance and low switching losses at an 800V withstand voltage level. The TO247 package offers excellent heat dissipation capability, suitable for high-power, high-reliability industrial applications. The combination of 20A continuous current, 220mΩ on-resistance, and 800V withstand voltage makes it an ideal replacement for traditional planar MOSFETs in high-voltage power supplies, inverters, and new energy systems.
