SPN1443S32RG-VB MOSFET Product Introduction
SPN1443S32RG-VB is a small, efficient N-channel MOSFET in SC70-3 package with extremely low on-resistance and excellent switching performance. With a drain-source withstand voltage of 20V, this MOSFET is suitable for low-voltage, high-efficiency power management and switching circuits. The gate-source threshold voltage (Vth) of SPN1443S32RG-VB is between 0.5V and 1.5V, which means that it can be started at a lower gate drive voltage and is suitable for low-voltage driven circuits. Its on-resistance (RDS(ON)) decreases significantly with the increase of gate voltage, from 40mΩ (VGS=4.5V) to 36mΩ (VGS=10V), making it lower loss and more efficient when switching. With a maximum drain current carrying capacity of 4A, this MOSFET is widely used in low-voltage, high-frequency power switching fields.
