Back to previous pageProduct introduction：
1. LR7843C-VB Product Introduction
LR7843C-VB is a high-efficiency single N-channel MOSFET in TO252 package, designed for medium and low voltage applications. Its maximum drain-source voltage (VDS) is 30V, and it can withstand a gate-source voltage (VGS) of ±20V, making it perform well in a variety of electronic circuits. The threshold voltage (Vth) of the device is 1.7V, ensuring fast turn-on at a lower gate voltage and excellent switching performance. The on-resistance (RDS(ON)) of the LR7843C-VB is 3mΩ at 4.5V and is lower to 2mΩ at 10V, which enables it to carry a drain current (ID) of up to 120A, suitable for high-load applications. Its Trench technology further improves the energy efficiency of the device, ensuring good thermal performance and heat dissipation capabilities.
