NTLUS3A18PZCTBG-VB Product details
Back to previous pageProduct introduction：
The NTLUS3A18PZCTBG-VB is a Single P-MOSFET deeply optimized for low-voltage power switch scenarios. The Trench process balances low conduction loss and high switching speed. The DFN6(2X2) package achieves an excellent balance between thermal performance and ultra-small footprint. The combination of 20V voltage rating, 10A current capability, and 20mΩ on-resistance makes it an ideal cost-reduction upgrade option to replace traditional SOP-8 packaged devices, especially suitable for high-density, portable, high-volume applications.
