PHB143NQ04T,118-VB Product details
Back to previous pageProduct introduction：
PHB143NQ04T,118-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. The Trench process balances ultra-low conduction loss with fast switching capability, and the TO263 package provides excellent heat dissipation performance and power density. The combination of 40V withstand voltage, 100A current capacity, and 5mΩ on-resistance makes it an ideal choice for high-current applications such as DC power supplies, motor drives, and battery protection, especially suitable for industrial-grade and automotive-grade systems with strict requirements for efficiency and reliability.
