Product Introduction: FDB8445-VB
FDB8445-VB is a high-performance N-channel MOSFET in TO263 package. It is designed for low voltage and high current applications and has a maximum drain-source voltage (VDS) of 40V. The gate-source voltage (VGS) of this MOSFET can reach ±20V, and the turn-on threshold voltage (Vth) is 2.5V. When VGS is 10V, its on-resistance (RDS(ON)) is only 5mΩ, and when VGS is 4.5V, it is 6mΩ, supporting a drain current of up to 100A. FDB8445-VB uses Trench technology to provide low on-resistance and high switching efficiency, suitable for a variety of high current and low power consumption application scenarios.
