**Application introduction and examples:**
1. **Power module:** Since VBQF1402 has low drain-source resistance and high drain current capacity, it is suitable for use in switching power supplies, DC-DC converters and other components in power modules. For example, in industrial power modules, VBQF1402 can be used as a power switch tube to achieve efficient power conversion and stable power output.

2. **Electric vehicle motor controller:** Due to its high current capacity and low resistance characteristics, VBQF1402 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, VBQF1402 can be used as a power switch tube to realize the drive and speed adjustment of the electric vehicle.

3. **Photovoltaic inverter:** VBQF1402 can also be used in photovoltaic 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 photovoltaic inverters, VBQF1402 can be used as a switching tube to achieve conversion and stable output of photovoltaic energy.
