HUF76423D3-VB Product details
Back to previous pageProduct introduction：
HUF76423D3-VB is a Single N-MOS deeply optimized for medium-voltage power switching scenarios. The Trench process balances low switching losses and high reliability, while the TO251 package achieves a good trade-off between heat dissipation capability and installation convenience. The combination of 60V withstand voltage, 40A current carrying capacity, and 35mΩ on-resistance makes it a reliable choice for low-voltage motor drives, power conversion, and automotive auxiliary systems, especially for applications with clear requirements for overcurrent margin and thermal performance.
