Infineon DD700N22K: A High-Performance 2200V Dual IGBT Module for Industrial Drives and Power Conversion
The relentless pursuit of higher efficiency, power density, and reliability in industrial and energy systems drives the continuous evolution of power semiconductor technology. At the forefront of this innovation is Infineon Technologies with its DD700N22K, a robust 2200V dual IGBT module engineered to meet the demanding requirements of modern high-power applications. This module represents a significant leap forward, offering system designers a superior combination of high voltage capability, low losses, and robust mechanical construction.
Engineered for Extreme Conditions and High Power
The DD700on22K is specifically designed for applications operating from a high DC-link voltage, typically found in advanced industrial drive systems and large-scale power conversion units. Its high voltage rating of 2200 V makes it an ideal choice for infrastructure such as high-power industrial motor drives, mining equipment, rolling stock traction systems, and renewable energy inverters, particularly in large solar and wind farms where medium-voltage connectivity is becoming standard. The module's dual-chip configuration allows for a compact and efficient design of common three-phase inverter topologies, simplifying system layout and improving thermal management.
Uncompromising Performance Through Advanced Technology
At the heart of the module's performance is Infineon's latest IGBT7 chip technology. This generation of IGBTs is renowned for achieving a remarkable optimal trade-off between conduction and switching losses. The result is a notably reduced Vce(sat) saturation voltage alongside soft and stable switching behavior. This translates directly into higher overall system efficiency, enabling developers to either reduce the size of heatsinks for a given power rating or increase the output power within the same form factor. The low loss characteristic also allows for higher switching frequencies, which can lead to a reduction in the size of passive filter components.
Furthermore, the module incorporates Emcon7 diodes as anti-parallel freewheeling diodes. These are optimized for low reverse recovery current and soft recovery, which minimizes voltage overshoots and electromagnetic interference (EMI). This is critical for ensuring stable operation and meeting stringent global EMI standards without excessive filtering.
Built for Reliability and Long Service Life
Beyond electrical performance, the DD700N22K is built to last. Its baseplate is constructed using ALSiC (Aluminum Silicon Carbide), a material celebrated for its thermal performance and a Coefficient of Thermal Expansion (CTE) that is closely matched to the ceramic substrate and silicon chips. This matching is crucial for maximizing power cycling capability and minimizing mechanical stress during temperature swings, a primary cause of failure in power modules. This robust construction ensures exceptional reliability even in the harsh environments typical of industrial settings.
The module also features a low-indunce stray inductance design within its housing. By minimizing parasitic inductance in the main current path, the module effectively suppresses destructive overvoltage spikes during fast IGBT turn-off, enhancing system safety and allowing designers to operate closer to the limits of the semiconductor.
