SSM3J340R,LF-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a compact battery-powered device with limited PCB area, yet you need to handle 5.6A of negative current and complex switching control. Ordinary P-channel MOSFETs either have high on-voltage drop or take up too much space. The VBsemi SSM3J340R,LF-VB is designed for this—it combines -30V withstand voltage, -5.6A current capability, and an on-resistance as low as 46mΩ into a miniature SOT23-3 package, allowing high-density power designs without compromise.
