SM1A54NHU-VB MOSFET Product Introduction
SM1A54NHU-VB is a single-tube N-type MOSFET in TO252 package. It has high performance and is particularly suitable for use in high-efficiency power conversion applications that require low RDS(ON) values. Its maximum drain-source voltage (VDS) is 100V, the gate-source voltage (VGS) is ±20V, it has a threshold voltage (Vth) of 1.8V, and when VGS=10V, the RDS(ON) is only 18mΩ, which makes it perform well in high-efficiency and high-power density applications. The SM1A54NHU-VB has a rated current of 45A and is suitable for various low-voltage switch mode power supplies (SMPS), DC-DC converters, electric vehicle chargers and other fields. It uses Trench technology and has low conduction losses and good thermal performance.
