SF3021LTR-VB Product details

Product introduction:

Product Introduction: SF3021LTR-VB

SF3021LTR-VB is a single N-channel MOSFET in SOT223 package with a drain-source voltage (VDS) of 60V and a maximum drain current (ID) of 4.5A. This MOSFET adopts Trench technology to provide low on-resistance (RDS(ON)). When VGS = 10V, RDS(ON) is only 76mΩ, with excellent conductivity and switching characteristics. Its threshold voltage (Vth) range is 1.7V, ensuring stable operation even at low gate voltage.

SF3021LTR-VB MOSFET is mainly used in applications requiring medium voltage and current control, such as power management, switching power supplies, and low-power battery management systems. With its low on-resistance, it can significantly reduce power loss and improve the energy efficiency of the system.
