STD38NF03LT4-VB Product Introduction
STD38NF03LT4-VB is a high-performance N-type MOSFET in TO252 package, designed for high current and high efficiency applications. With a maximum drain-source voltage (VDS) of 30V and a maximum drain current (ID) of 70A, it is suitable for low voltage and high current power management and switching applications. With an on-resistance (RDS(ON)) of 9mΩ (VGS = 4.5V) and 7mΩ (VGS = 10V), this MOSFET shows excellent conductivity and effectively reduces switching losses and heat generation. The use of Trench technology provides lower conduction losses and higher switching speeds, making it particularly suitable for high-efficiency power management systems, power amplifiers, and motor control. With its low on-resistance and high current carrying capacity, the STD38NF03LT4-VB performs particularly well in applications requiring fast switching and low losses.
