Product Introduction
**STS2DPF20V-VB** is a bipolar MOSFET (Dual-P+P-Channel) in a **SOP8** package. It integrates two P-type MOSFETs and is suitable for applications that require load switching, reverse current protection, and efficient current control. The maximum **VDS** of this MOSFET is **-20V**, which is suitable for low-voltage, high-current switching applications. The maximum drain current is **-8.9A**, which is suitable for low-voltage power supplies and signal processing circuits. Its **RDS(ON)** is 18mΩ at **VGS=4.5V** and 16mΩ at **VGS=10V**. It has a very low on-resistance, which can reduce power loss and improve overall efficiency. The threshold voltage (**Vth**) is **-1.2V**, which allows the MOSFET to switch stably under low voltage drive. Using **Trench technology**, the ST2DPF20V-VB has a wide range of application scenarios in high-performance and low-power designs, and is particularly suitable for power management and switching applications that require low power consumption and high conductivity.
