IRLB8748PBF-VB MOSFET Product Introduction
The IRLB8748PBF-VB is a high-performance single N-channel MOSFET in a TO-220 package, designed for high power and high efficiency applications. The maximum drain-source voltage (VDS) of this MOSFET is 30V, and it supports a gate drive voltage (VGS) of ±20V. The IRLB8748PBF-VB has an extremely low on-resistance (RDS(ON)), which is 4mΩ at a gate voltage of 4.5V and 3mΩ at a gate voltage of 10V, providing excellent current conduction performance and high efficiency. Its maximum continuous drain current (ID) is 120A, enabling it to handle high current applications without significantly increasing power consumption or generating excessive heat. This MOSFET uses Trench technology, ensuring its superior performance under high switching frequency and high load conditions.
