After rigorous aging testing and reliability verification, the mean time between failures (MTBF) exceeds 100000 hours, reducing equipment maintenance costs and downtime.

3. Advantages of system integration

Asymmetric structure and integrated gate control technology simplify circuit design, reduce the number of peripheral devices, and lower system costs and volume. At the same time, we provide comprehensive solutions for driving and protection circuits, which facilitate integration with other power electronic devices and systems, shorten product development cycles, and improve system design efficiency.

4. Green and energy-saving

The low switching loss and conduction loss characteristics effectively reduce system energy consumption, which is in line with the development trend of green energy conservation. In large-scale applications, it can significantly reduce the energy consumption and carbon emissions of the power system, providing strong support for enterprises to achieve energy-saving and emission reduction goals.

Installation requirements

Environmental conditions: The installation environment should be kept dry, clean, and free of corrosive gases and dust. The ambient temperature should be controlled within the range of -40 ℃ to+50 ℃, and the relative humidity should not exceed 95% (without condensation).

Electrical connection: Strictly follow the electrical schematic for wiring, ensure correct connection of positive and negative poles, secure and reliable wiring terminals, and avoid loose connections causing poor contact and heating. At the same time, to reduce electromagnetic interference, the gate control signal line should use shielded cables and maintain an appropriate distance from the main circuit cable.

Heat dissipation design: The device needs to be installed on an efficient heat dissipation device, such as a radiator or water-cooled heat dissipation module. Apply uniform thermal grease between the device and the heat sink during installation to ensure good heat conduction. The heat dissipation capacity of the heat sink should meet the heat dissipation requirements of the device at maximum power consumption, ensuring that the operating junction temperature of the device does not exceed the rated value.
