K3813-VB Product details
Back to previous pageProduct introduction：
1. K3813-VB MOSFET Product Introduction:
K3813-VB is a single N-channel MOSFET in TO251 package with a drain-source voltage (VDS) of 40V and a gate-source voltage (VGS) of ±20V. It uses advanced trench technology to achieve excellent conduction characteristics at a lower gate drive voltage. The main feature of this device is the low on-resistance (RDS(ON)), which is 6.5mΩ at a VGS of 4.5V and further reduced to 5mΩ at a VGS of 10V, and can withstand a maximum current of 85A. This low on-resistance and high current carrying capacity make it suitable for efficient power management and power conversion applications.
