STU2240NL-VB Product details
Back to previous pageProduct introduction：
**Product Introduction: STU2240NL-VB**
STU2240NL-VB is a single N-type MOSFET in TO252 package with a maximum drain-source voltage (VDS) of 40V and a maximum drain current (ID) of 55A, designed for high-efficiency power switching applications. This MOSFET uses Trench technology to provide excellent performance at low on-resistance (RDS(ON)=14mΩ @ VGS=4.5V, 12mΩ @ VGS=10V). Its lower on-resistance effectively reduces power loss and improves the energy efficiency of the overall system. The gate-source threshold voltage (Vth) of STU2240NL-VB is 2.5V, which is suitable for driving standard control signals and is widely used in power conversion, power management, DC-DC converters, and motor drives.
