LR3802-VB Product details
Back to previous pageProduct introduction：
**
LR3802-VB is a high-performance 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 20V, a gate-source voltage (VGS) range of ±20V, a turn-on threshold voltage (Vth) of 0.5V to 1.5V, and an extremely low on-resistance (RDS(ON)), which is 6mΩ at 2.5V VGS and drops to 4.5mΩ at 4.5V VGS. The maximum drain current (ID) can reach 100A, and the use of advanced trench technology makes it superior in high efficiency and thermal management, suitable for various high-power density power management applications.
