LIB4343-VB Product details
Back to previous pageProduct introduction：
1. Product Introduction of LIB4343-VB MOSFET
LIB4343-VB is a high-efficiency N-channel MOSFET in TO220F package, designed for medium voltage and high current applications. The device has a maximum drain-source voltage (VDS) of 60V and a gate-source voltage (VGS) rating of ±20V, suitable for a wide range of power supplies and drive circuits. The turn-on threshold voltage (Vth) is 1.7V, and it can be turned on at a low gate drive voltage. The on-resistance (RDS(ON)) is 27mΩ at VGS=10V, ensuring low conduction losses at high currents, and the maximum drain current is 45A. This MOSFET is manufactured based on trench technology, with higher switching efficiency and low energy consumption, and is widely used in power management and motor control.
