PMPB19XP-VB Product details
Back to previous pageProduct introduction：
PMPB19XP-VB is a Single P-MOSFET deeply optimized for low-voltage power switching scenarios. Trench technology balances low switching losses and high reliability, while the DFN6(2X2) package achieves an excellent balance between heat dissipation and board footprint. The combination of -20V voltage tolerance, -10A current capability, and 20mΩ on-resistance makes it an ideal cost-effective upgrade to replace traditional SOP-8 or SOT23 packaged devices, especially suitable for high-density, high-volume applications.
