Mingjiada Supply Infineon IMBG75R, IMDQ75R And IMZA75R Silicon Carbide CoolSiC™ MOSFET For AI Server Applications

With the rapid expansion of AI computing infrastructure, server power supplies are subject to stringent requirements regarding power density, conversion efficiency and high-temperature reliability. Thanks to their trench silicon carbide (SiC) process, Infineon’s second-generation 750V CoolSiC™ MOSFETs (IMBG75R, IMDQ75R and IMZA75R) have become the core power devices for AI server power supplies and data centre power systems.

Shenzhen Mingjiada Electronics Co., Ltd. — offers spot supply and stock buy-back services for Infineon’s three silicon carbide CoolSiC™ MOSFET series: IMBG75R, IMDQ75R and IMZA75R. These devices are key components in the construction of energy-efficient AI server power supplies.

I. IMBG75R Series Silicon Carbide CoolSiC™ MOSFETs (PG‑TO263‑7)

Details: Suitable for SMT automated production lines, covering the medium-power range for server power supplies; 7-pin configuration with a Kelvin source, featuring an integrated drive source pin, suitable for AI server power supplies, industrial energy storage, photovoltaic inverters and more.

Key Applications in AI Servers

With the surge in demand for AI computing power, server power supplies are evolving towards ultra-high efficiency and high power density. Thanks to their ultra-low switching losses and excellent high-temperature stability, these three MOSFETs have become the preferred choice for next-generation AI server power supply systems.

They are primarily used in the following key components of AI server power supplies:

Totem-pole PFC (Power Factor Correction) circuits

LLC resonant converters

High-Voltage Direct Current (HVDC) Power Supply Architecture

AI server power supply systems utilising these SiC MOSFETs can achieve efficiencies of over 96.71 per cent, significantly reducing both electricity costs and cooling energy consumption in data centres.

Infineon’s IMBG75R, IMDQ75R and IMZA75R series of CoolSiC™ MOSFETs are power devices specifically designed for high-power-density, high-efficiency applications, making them particularly suitable for AI server power supplies. Mingjiada Electronics provides a one-stop service for these devices, ranging from spot supply to inventory buyback.

Spot supply: We supply brand-new, genuine Infineon CoolSiC™ MOSFETs, supporting both bulk orders and small-batch samples.

Stock Buyback: We offer long-term, high-value buyback services worldwide for genuine, original IMBG75R, IMDQ75R and IMZA75R series stock and obsolete components, covering both industrial-grade (IMB/IMD prefixes) and automotive-grade (AIM/IMZ prefixes) variants, such as IMBG75R007M2H, AIMDQ75R004M2H, IMZA75R007M2H, etc.
