Back to previous pageProduct introduction：
1. LR8503-VB Product Introduction
LR8503-VB is a single N-channel MOSFET in TO252 package, designed for low to medium voltage applications. Its drain-source withstand voltage (VDS) is 30V, which is suitable for power management and load switching operations in various electronic systems. The threshold voltage (Vth) of the device is 1.7V, which can start switching operation at a lower gate drive voltage. The on-resistance of LR8503-VB is low, 9mΩ@VGS=4.5V and 7mΩ@VGS=10V, respectively, and the maximum drain current can reach 70A. These parameters make it perform well in various applications with high requirements for efficiency and current handling capabilities.
