Product introduction：
**STM102D-VB MOSFET Product Introduction**
STM102D-VB is a **bipolar N+P channel MOSFET** using **Trench technology**, with **SOP8** package, widely used in high-efficiency power management, electric drive and signal switching. The **drain-source voltage (VDS)** of this MOSFET can reach **±100V**, supporting high voltage operation, suitable for applications requiring bipolar operation and high voltage processing. Its maximum **drain current (ID)** is **2.2A** (N channel) and **-1.9A** (P channel), and it has **low on-resistance (RDS(ON))**, and has excellent conductivity at different gate voltages. The STM102D-VB provides low on-resistance of 260mΩ and 240mΩ at gate voltages of 4.5V and 10V, corresponding to N-channel and P-channel, respectively, making it an ideal choice for power control, switching power supplies and other power electronics applications.
