LR7821-VB Product details
Back to previous pageProduct introduction：
**
LR7821-VB is a high-efficiency single N-channel power MOSFET in TO252 package, designed for low voltage and high current applications. The device has a drain-source voltage (VDS) of 30V, a gate-source voltage (VGS) range of ±20V, and a turn-on threshold voltage (Vth) of 1.7V, with excellent turn-on characteristics. At VGS of 4.5V, the on-resistance (RDS(ON)) is 6mΩ, and at VGS of 10V, RDS(ON) drops to 5mΩ, supporting a maximum drain current (ID) of up to 80A. LR7821-VB uses advanced trench technology to ensure high efficiency and good thermal management, suitable for high power density power conversion and switching applications.
