SSM3J168F,LXHF-VB Product details
Back to previous pageProduct introduction：
SSM3J168F,LXHF-VB is a Single P-MOS optimized for low-power, high-voltage switching scenarios, using Trench technology with low conduction loss and high reliability switching characteristics. The SOT23-3 package strikes a good balance between compact footprint and heat dissipation performance. The combination of 60V withstand voltage, 0.5A current capability, and 3Ω-level on-resistance makes it particularly suitable for battery-powered devices, signal switching, and high-voltage auxiliary circuits, serving as an ideal high-density alternative to traditional larger P-MOS packages.
