Applications and module examples:

1. **Power tools**
- The high conductivity and low on-resistance of the STP90NS04ZC-VB make it very suitable for use in power tools, especially in situations where high current and low power loss are required. For example, in tools such as electric drills and electric wrenches, this MOSFET can effectively drive the motor to ensure efficient operation and long-term use of the equipment.

2. **Switching power supply (SMPS)**
- In switching power supply modules, the STP90NS04ZC-VB can be used as an efficient switching element to provide lower on-resistance, thereby reducing the switching loss of the power supply. Especially in low-voltage, high-current situations, such as low-voltage DC power supplies or communication power supply modules, the use of this MOSFET can significantly improve system efficiency and reduce energy waste.

3. **Battery management system (BMS)**
- Battery management systems usually require efficient current control and protection during charging and discharging. The low RDS(ON) characteristics of the STP90NS04ZC-VB enable low losses and fast response during battery charging, making it suitable for mobile devices, energy storage systems and other fields.

4. **Electric Vehicles (EV)**
- This MOSFET is also suitable for the power system of electric vehicles, especially in battery pack management and motor control modules. It can withstand high currents and work in high temperature environments, suitable for DC-DC converters and motor drive modules in electric vehicles.

5. **Home Appliances**
- In the home appliance field, the STP90NS04ZC-VB can be used to control the drive and power conversion of motors to ensure the efficient operation of home appliances (such as washing machines, electric fans, air conditioners, etc.). For example, it is used to provide reliable switching control in inverter circuits.

While providing stable current control, this type of MOSFET is widely used in many high-efficiency and high-current load fields due to its low on-resistance, high voltage resistance and excellent temperature performance.
