DMP4065SQ-7-VB Product details
Back to previous pageProduct introduction：
**VBsemi DMP4065SQ-7-VB is a Single P-Channel MOSFET manufactured using Trench technology, designed for medium and low voltage load switching and power management applications. Its SOT23-3 small package balances heat dissipation and layout flexibility, suitable for space-constrained high-density PCB designs. The device provides stable switching characteristics within a -40V drain-source voltage range. Its gate drive is compatible with common 3.3V/5V logic levels, facilitating direct system drive. The low on-resistance characteristic effectively reduces conduction losses, improving overall conversion efficiency.**
