With the rapid development of AI computing clusters, cloud computing and data centres, the demands placed on server power supplies in terms of power density, conversion efficiency and long-term reliability have reached unprecedented levels. As the core of power electronic conversion, the performance of power MOSFETs directly influences the overall energy efficiency and temperature rise behaviour of the system.
Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as ‘Mingjiada Electronics’), an authorised independent distributor of Infineon with nearly three decades of industry experience, has long supplied large volumes of genuine Infineon CoolMOS™ N-channel power MOSFETs. Drawing on our stock held at distribution centres in Hong Kong and Shenzhen, we are committed to providing high-performance power switching solutions with low on-resistance and high switching speeds for the server, telecommunications and industrial power supply sectors.
Core CoolMOS™ Product Series for Server Power Supplies
In typical server power supply applications (such as PFC boost, LLC resonant and secondary synchronous rectification), the Infineon CoolMOS™ series utilises innovative superjunction technology to achieve extremely low switching and conduction losses in high-voltage applications. Mingjiada Electronics supplies the following mainstream series optimised for server applications:
1. Next-generation CoolMOS™ 8 series: Setting the benchmark for energy efficiency
As Infineon’s latest generation of high-voltage super-junction MOSFETs, the 600V CoolMOS™ 8 is specifically designed to meet the stringent high-efficiency requirements of data centres.
Performance advantages: Compared to the CoolMOS™ CFD7 series, gate charge (Qg) is reduced by 18%; and 33 per cent lower than the P7 series, significantly improving efficiency at both light and full loads.
Application value: This series has been widely adopted in AI servers and 5.5kW Titanium-rated power supply solutions from leading manufacturers such as Great Wall Power and Mami Electric, delivering higher power density and cost-effectiveness.
2. CoolMOS™ P7 Series: Balancing Performance and Ease of Use
This series strikes an excellent balance between switching losses and ease of drive, and is widely used in PFC hard-switching and LLC soft-switching topologies for server power supplies.
Popular models: Mingjiada primarily supplies the IPW60R060P7 (600V/60mΩ, TO-247 package) and the IPP60R120P7 (600V/120mΩ, TO-220 package). Taking the Quanta 800W CRPS server power supply as an example, it utilises CoolMOS P7 series devices in both the PFC and LLC stages.
3. CoolMOS™ C7/C3 Classic Models
For high-efficiency industrial adapters and legacy server power supply designs, Mingjiada offers classic models such as the SPW20N60C3, IPW60R041C6, which strike a perfect balance between voltage rating and efficiency, making them particularly suitable for ultra-high-efficiency PFC circuits.
Why choose Mingjiada for server power supply design?
Guarantee of genuine products: Mingjiada Electronics is certified under the ISO 9001 quality management system, ensuring that all incoming goods are free from refurbished or counterfeit items.
Rapid response with stock on hand: For commonly used part numbers in server power supplies (such as IPW60R060P7, IPP60R120P7 and BSC016N06NS), we support sample requests and small-batch procurement to resolve your urgent stock shortages.
