Product Introduction
BUK9209-40B-VB is a high-performance single N-channel MOSFET in a TO252 package. The device has a drain-source voltage (VDS) of 40V and a gate-source voltage (VGS) tolerance of ±20V. Its threshold voltage (Vth) is 2.5V. At a VGS of 4.5V, its on-resistance (RDS(ON)) is 6mΩ, and at a VGS of 10V it is 5mΩ, supporting a continuous drain current (ID) of up to 85A. BUK9209-40B-VB uses Trench technology to provide excellent switching performance and low conduction losses, making it ideal for applications requiring medium to high currents and lower voltages.
