PMV31XN,215-VB Product details
Back to previous pageProduct introduction：
The PMV31XN is a Single N-MOS deeply optimized for low-voltage power switching scenarios. The Trench process balances low switching losses with high reliability, and the SOT23-3 package strikes a balance between heat dissipation and board space. The combination of 20V withstand voltage, 6A current capacity, and 28mΩ on-resistance (@4.5V) makes it an ideal cost-reducing alternative to traditional DPAK or SOP-8 package devices, especially suitable for high-density, high-volume applications.
