Product introduction：
**UM3801-VB Product Introduction**
UM3801-VB is a bipolar MOSFET in **SOP8** package with **N-Channel** and **P-Channel** configurations. The device has a **±30V** drain-source voltage (VDS) and **±8A** maximum drain current (ID), suitable for various power switching applications. Its **gate threshold voltage (Vth)** is **1.6V** (N-Channel) and **-1.7V** (P-Channel), respectively, which enables it to start at a lower gate drive voltage to meet the needs of different control circuits. Manufactured using **Trench** technology, it has excellent switching performance and low on-resistance. Specifically, the on-resistance of **N-Channel** is **24mΩ** at **VGS = 4.5V**, **18mΩ** at **VGS = 10V**; the on-resistance of **P-Channel** is **50mΩ** at **VGS = 4.5V**, **40mΩ** at **VGS = 10V**. This bipolar MOSFET is suitable for power management and switch control systems with low power loss and compact design.
