1. LI3705N-VB Product Introduction
LI3705N-VB is a high-performance single-channel N-type MOSFET in TO220F package, designed for medium power applications. Its maximum drain-source voltage (VDS) is 60V, and it can withstand a drain current (ID) of up to 70A, making it very suitable for use in power management and motor control. The device has a threshold voltage (Vth) of 2.5V and has good switching performance. At VGS = 4.5V, the on-resistance (RDS(ON)) of LI3705N-VB is 12mΩ, and it drops to 10mΩ at VGS = 10V, showing extremely low conduction losses. Using trench technology (Trench), this MOSFET not only has superior thermal management capabilities, but also maintains stable performance at high frequency operation, making it suitable for a variety of industrial and consumer electronics applications.
