CPH3314-TL-H-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a compact battery-powered device that requires efficient switching of a negative voltage rail, yet PCB space is extremely limited. Ordinary P-channel MOSFETs either have high on-voltage drop or complex drive logic. The VBsemi CPH3314-TL-H-VB is designed for this—it combines -30V withstand voltage, -5.6A current capability, and an on-resistance of only 46mΩ into a miniature SOT23-3 package, making negative voltage power management simple and effortless.
