SI080P04L-13P-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a compact power management circuit with extremely limited board space, yet you need to handle -3.6A load switching and a -40V voltage rail. Ordinary PMOS transistors are either too large in package or have high conduction losses. VBsemi SI080P04L-13P-VB is designed for this exact scenario—it integrates a -40V withstand voltage, -3.6A current capability, and an on-resistance as low as 71mΩ into a miniature SOT23-3 package, allowing negative voltage power supply designs to save space while maintaining excellent efficiency.
