SSM6K387R,LF-VB Product details
Back to previous pageProduct introduction：
**Product Introduction**SSM6K387R,LF-VB is a Single N-MOS optimized for high-voltage power switching applications. The Trench technology strikes a good balance between conduction loss and switching speed, while the SOT23-6 package enables efficient heat dissipation in a compact footprint. The combination of 100V withstand voltage, 3.2A current carrying capacity, and 95mΩ on-resistance makes it an ideal cost-reduction alternative to traditional SOP-8 or DPAK package devices, particularly suitable for high-density, reliable power control applications.
