SSM3J356R,LXHF-VB Product details
Back to previous pageProduct introduction：
Imagine: You are designing a compact battery-powered device with extremely limited PCB space, yet you need a P-Channel MOSFET capable of handling negative power rail switching. Ordinary devices either lack sufficient voltage tolerance or have high conduction losses. VBsemi SSM3J356R,LXHF-VB is designed for this—it packs -60V withstand voltage, -4.5A current capability, and an on-resistance as low as 70mΩ into the small SOT23-3 package, making high-side negative switching design no longer a compromise.
