PHX18NQ20T,127-VB Product details
Back to previous pageProduct introduction：
PHX18NQ20T,127-VB is a Single N-MOS deeply optimized for medium-to-high voltage power switching scenarios. The Trench process achieves a good balance between conduction loss and switching speed, while the TO220F fully isolated package combines heat dissipation capability with ease of installation. The combination of 200V withstand voltage, 18A current carrying capacity, and 200mΩ on-resistance makes it a reliable choice for industrial power supplies, motor drives, and high-voltage auxiliary circuits, especially suitable for power conversion applications requiring high voltage margin and low thermal resistance.
