Introduction: As the demand for energy efficiency and power density continues to rise in new energy vehicles, photovoltaic energy storage, and AI data centers, silicon carbide (SiC) is gradually replacing traditional silicon-based devices as the core technology for medium- to high-power applications. As an authorized independent distributor of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. specializes in supplying the full range of Infineon CoolSiC™ MOSFET products.
The Era of Silicon Carbide: Why Choose CoolSiC™?
In high-voltage, high-frequency, and high-temperature applications, traditional silicon-based IGBTs are reaching their physical limits. Thanks to its wider bandgap, silicon carbide enables devices to withstand higher voltages and temperatures while achieving lower switching losses. Based on advanced trench-gate semiconductor technology, Infineon’s CoolSiC™ MOSFETs are specifically designed to optimize for the lowest losses and highest operational reliability in these applications.
Compared to traditional solutions, the core value of CoolSiC™ technology lies in:
Improved system efficiency: On-resistance can be reduced by more than 50%, boosting system efficiency by 3–5%; in photovoltaic inverters, conversion efficiency of over 99% can be achieved.
Increased power density: Support for higher switching frequencies significantly reduces the size of transformers and passive components, making it ideal for compact designs.
High-temperature stability: Supports operation at junction temperatures as high as 175°C or even 200°C, reducing cooling system costs.
Product Portfolio Overview: Covering Multiple Voltage Ratings and Application Requirements
Infineon’s CoolSiC™ product portfolio offers a wide range of voltage ratings and packaging options to meet diverse requirements from industrial to automotive electronics.
Discrete MOSFETs
CoolSiC™ discrete devices cover voltage ratings of 650V, 750V, 1200V, 1700V, and 2000V, with on-resistance ranging from 7 mΩ to 1000 mΩ.
650V Series: Optimized switching behavior, suitable for server power supplies, telecommunications equipment, and motor drives.
750V/1200V Series: Offers industrial and automotive-grade certification (AEC-Q101), suitable for on-board chargers (OBC), auxiliary inverters, and uninterruptible power supplies (UPS).
1700V/2000V Series: Designed specifically for high-voltage applications, such as fast DC charging stations, energy storage systems (ESS), and centralized solar inverters.
Power Modules
For high-power applications, CoolSiC™ offers a variety of module topologies and packages:
Half-Bridge Modules (1200V/2000V): Suitable for electric vehicle charging, fuel cell DC-DC boost converters, and photovoltaic inverters.
Easy 1B/2B Package Series: Suitable for industrial applications such as solar power, UPS, energy storage, and medical equipment.
62mm Packaged Modules (1200V): This module series features a half-bridge configuration with a typically low stray inductance design (approximately 20 nH) and is specifically designed for high-power, high-frequency applications such as EV charging, energy storage systems, servers and IT infrastructure, and commercial induction cooktops.
In-Depth Analysis of Core Application Scenarios
1. New Energy Vehicles and Charging Infrastructure
In electric vehicle main drive inverters, on-board chargers (OBCs), and DC fast-charging stations, CoolSiC™ is key to extending range and reducing charging time. Its high-voltage withstand capability (1200V and above) and low-loss characteristics significantly improve the efficiency of charging modules, making them suitable for ultra-fast and fast-charging scenarios.
2. Photovoltaic Power Generation and Energy Storage Systems
In solar inverters and power conversion systems (PCS) for energy storage, CoolSiC™ modules can boost conversion efficiency to over 99%, significantly reducing energy loss. Their high reliability also meets the requirements of energy storage systems for long service life and maintenance-free operation.
3. Data Centers and AI Server Power Supplies
With the explosive growth in demand for AI computing power, data center power consumption has become a major challenge. The high-frequency, high-efficiency characteristics of CoolSiC™ MOSFETs enable more streamlined server power supply (PSU) architectures, which not only improve energy conversion efficiency but also reduce the size of power supplies, freeing up more deployment space in server rooms.
4. Industrial and Infrastructure
From UPS systems and auxiliary traction power supplies to commercial induction cooktops, the applications of CoolSiC™ in the industrial sector continue to expand. Particularly in high-power-density scenarios, it effectively reduces cooling costs and enhances overall system reliability.
