**Application introduction and examples:**
1. **Power module:** Since VBFB1405 has high drain current capacity and low drain-source resistance, it is suitable for use in switching power supplies, DC-DC converters and other components in power modules. For example, in industrial power modules, VBFB1405 can be used as a power switch to achieve efficient power conversion and stable power output.

2. **Electric vehicle motor controller:** Due to its high current capacity and low resistance characteristics, VBFB1405 is suitable for use in electric vehicle motor controller modules, such as electric vehicle motor drive controllers, battery management systems, etc. For example, in the motor controller of an electric vehicle, VBFB1405 can be used as a power switch tube to realize the drive and speed adjustment of the electric vehicle.

3. **Solar Inverter:** VBFB1405 can also be used in solar inverter modules, such as solar inverters, photovoltaic power generation systems, etc. Its low impedance and high current capacity ensure efficient energy conversion and stable power output in photovoltaic systems. For example, in solar inverters, VBFB1405 can be used as a switching tube to achieve conversion and stable output of solar energy.
