Back to previous pageProduct introduction：
**Product Introduction: STU3055NL-VB**
STU3055NL-VB is a high-performance single N-type MOSFET in TO252 package, designed for low-voltage and high-current switching applications. It has a maximum drain-source voltage (VDS) of 20V and a maximum drain current (ID) of 100A. This MOSFET uses Trench technology and has a very low on-resistance (RDS(ON) is only 4.5mΩ @ VGS=4.5V), which can significantly reduce power loss and improve system efficiency. Its gate-source threshold voltage (Vth) ranges from 0.5V to 1.5V, which is suitable for low-voltage drive control. It is particularly suitable for high-current, high-power switching power supplies, DC-DC converters, load switches, drive circuits and other fields.
