Product introduction：
1. MMBT7002K-VB Product Introduction
MMBT7002K-VB is a **single N-channel (N-Channel) MOSFET**, using **SOT23-3** package, with high performance and compact design. The device is based on **trench technology** and can operate normally at a higher drain-source voltage (VDS), up to 60V. Its gate-source voltage (VGS) range is ±20V, suitable for a variety of power management and switching applications. With optimized on-resistance (RDS(ON)), the device is 3100mΩ and 2800mΩ at gate voltages of 4.5V and 10V, respectively, making it superior in energy saving and efficient operation. The maximum drain current (ID) is 0.3A, making the device very suitable for low-power applications.
