With the exponential growth in computing power requirements for training and inference in large-scale artificial intelligence models, the power consumption of AI servers and data centres is approaching the megawatt level. To address the energy consumption challenges posed by high computing power, high-voltage direct current (HVDC) power supply architectures and high-efficiency power devices have become essential for the industry.
Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as ‘Mingjiada Electronics’), a specialist independent distributor with nearly thirty years’ experience in the electronic components supply chain, is currently seeking to purchase, on a long-term basis and at premium prices, Infineon’s second-generation 750V CoolSiC™ MOSFET G2 series silicon carbide power devices from suppliers worldwide.
In response to the current trend towards higher power density and higher conversion efficiency in AI server power supplies, Mingjiada is prioritising the acquisition of the following genuine, original equipment manufacturer (OEM) stock and obsolete inventory. The full list of models is as follows:

Why do AI servers require silicon carbide (SiC) MOSFETs?
In AI data centres, power distribution losses and cooling costs constitute a major portion of operating expenditure. Compared to traditional silicon-based devices, 750V CoolSiC™ MOSFETs offer extremely low switching and conduction losses. Empirical data shows that AI server power supply systems utilising SiC solutions can achieve efficiencies of over 96.71 per cent, significantly reducing electricity bills and cooling energy consumption.
Furthermore, with the widespread adoption of 800V HVDC architectures, 750V-rated SiC MOSFETs demonstrate exceptional stability in battery backup units (BBUs) and power supply units (PSUs), ensuring system safety under high loads.
