Product Introduction
**UMBF170-VB** is a high-efficiency unipolar N-channel MOSFET in a SOT23-3 package designed for low-power applications. It has a drain-source voltage (VDS) of 60V, which is suitable for medium and low voltage switching and current control tasks. The threshold voltage (Vth) of this product is 1.7V, which is suitable for low-voltage control applications and can switch effectively at a lower gate-source voltage. The on-resistance (RDS(ON)) is 2800mΩ at VGS=10V and 3100mΩ at VGS=4.5V, providing lower power loss and good current transfer efficiency. The maximum drain current (ID) of UMBF170-VB is 0.3A, which is very suitable for low-power and low-current control scenarios. This model adopts **Trench technology** to effectively reduce switching losses and improve working efficiency.
