LR8721-VB MOSFET Product Introduction
LR8721-VB is a high-performance single N-channel MOSFET in a TO252 package, designed for low-voltage, high-current applications. Its maximum drain-source voltage (VDS) is 30V, the gate drive voltage range is ±20V, and the threshold voltage is 1.7V. The on-resistance is 3mΩ at a gate drive voltage of 4.5V, and the on-resistance is as low as 2mΩ at a gate drive voltage of 10V, capable of providing up to 100A of continuous current. These features give the LR8721-VB excellent performance in high-efficiency switching circuits and power management applications, especially in systems that need to handle high currents and low power consumption. With trench technology, it is particularly effective in reducing conduction losses and improving the overall energy efficiency of the system.
