LR7811WC-VB Product details
Back to previous pageProduct introduction：
Product Introduction:
LR7811WC-VB is a high-performance single N-channel MOSFET that uses advanced trench technology and is packaged in a TO252 package. The maximum drain-source voltage (VDS) of this MOSFET is 30V, making it suitable for low to medium voltage switching applications. Its gate-source voltage (VGS) can reach ±20V, and its turn-on voltage (Vth) is 1.7V. At a gate-source voltage of 10V, its on-resistance (RDS(ON)) is as low as 2mΩ, and 3mΩ at 4.5V, capable of supporting a continuous drain current (ID) of up to 100A. This excellent performance enables the LR7811WC-VB to perform well in various power management and drive applications, and is particularly suitable for high-efficiency power conversion and control circuits.
