Product introduction：
**SSM3K7002BF-VB MOSFET Product Introduction**
SSM3K7002BF-VB is a single N-channel MOSFET in a SOT23-3 package, designed for medium and low voltage and low power applications. Its drain-source withstand voltage (Vds) is 60V, the gate-source voltage (Vgs) is ±20V, and it has a low threshold voltage (Vth) of 1.7V, ensuring that it can be turned on at a lower gate voltage. This MOSFET uses Trench technology to provide a lower on-resistance (Rds(on)). The on-resistance is 2800mΩ at Vgs=10V, which is very suitable for switching control in low-power applications. The maximum drain current (Id) of this MOSFET is 0.3A, which is suitable for applications requiring low power consumption and small packaging.
