RSR020P05TL-VB Product details
Back to previous pageProduct introduction：
**Product Introduction** Imagine this: You are designing a portable battery-powered device that requires precise power switch control on the load side, but is constrained by limited PCB space and strict power budgets. Traditional PMOS transistors are either too large in package or have high conduction losses. VBsemi RSR020P05TL-VB is designed for this exact scenario—it integrates a -40V withstand voltage, a -3.6A current capability, and an on-resistance as low as 71mΩ into the miniature SOT23-3 package, making high-side switch design simple and efficient.
