Product Introduction
**SI4933DY-T1-E3-VB** is a dual-channel MOSFET (field effect transistor) produced by **Vishay**, using **SOP8** package, designed for low voltage and high efficiency applications. The device has a **P+P-Channel** configuration and supports an operating range of **VDS = -20V** and **VGS = ±20V**. Its threshold voltage (Vth) is **-1.2V**, which is very suitable for operation under low gate voltage conditions. The **RDS(ON)** of this MOSFET is **18mΩ** at **VGS = 4.5V** and **16mΩ** at **VGS = 10V**, respectively, providing excellent low on-resistance, ensuring lower power loss and efficient current transfer. The maximum drain current (ID) is **-8.9A**, which is suitable for circuits requiring higher power control.
