Infineon FS75R12KE3G IGBT Module

Infineon FS75R12KE3G | High-Efficiency 1200V IGBT Six-Pack Module

The Infineon FS75R12KE3G is a high-performance 1200V, 75A six-pack IGBT module engineered for demanding power conversion applications. Housed in the industry-proven EconoPACK™ 3 package, this module integrates Infineon's advanced IGBT4 Trench Field-Stop technology to deliver a superior balance of efficiency, robustness, and power density. It is an ideal solution for designers of motor drives, uninterruptible power supplies (UPS), and solar inverters seeking to enhance system performance and reliability.

Technical Deep Dive: Where Performance Meets Precision

Advanced IGBT4 Trench Field-Stop Technology

At the heart of the FS75R12KE3G lies the fourth-generation Trench Field-Stop (TFS) IGBT technology. This isn't just an incremental update; it's a fundamental redesign that directly addresses the core challenges of power electronics design:

• Reduced Conduction Losses: The IGBT4 chip features an exceptionally low collector-emitter saturation voltage (Vce(sat)). For the end-user, this translates directly into lower conduction loss during operation, meaning less energy is wasted as heat. This allows for smaller heatsinks, higher power density, and reduced operational costs.
• Optimized Switching Behavior: The technology provides a finely tuned balance between turn-on and turn-off losses (Eon and Eoff). This optimization is crucial for achieving high efficiency in systems operating at moderate switching frequencies (typically up to 20 kHz), while also controlling EMI generation.

EconoPACK™ 3: Integration and Reliability

The EconoPACK™ 3 package of the FS75R12KE3G is more than just a housing; it’s an integrated solution. Featuring a standard IGBT six-pack configuration and an integrated NTC thermistor for temperature monitoring, it simplifies both mechanical and electrical design, reducing assembly time and component count.

Application Scenarios & Real-World Value

• Industrial Motor Drives: In variable frequency drives (VFDs), the high efficiency of the Infineon FS75R12KE3G minimizes heat dissipation, enabling more compact and cost-effective drive designs. Its robustness ensures long-term reliability even under harsh industrial conditions.
• Uninterruptible Power Supplies (UPS): For mission-critical UPS systems, every watt of saved energy counts. The low static and dynamic losses of this module enhance overall system efficiency, reducing cooling requirements and improving the total cost of ownership (TCO).
• Solar & Renewable Energy Inverters: Maximizing energy harvest is the primary goal in solar applications. The superior performance of the FS75R12KE3G ensures that a greater percentage of DC power from the solar panels is converted into usable AC power, directly increasing the system's return on investment.
• Welding Equipment: The module's ability to handle high currents and its thermal stability make it a reliable choice for the power stages of modern inverter-based welding machines, delivering consistent and precise power control.

Selection & Comparison Insights: Why Choose the FS75R12KE3G?

When compared to older Non-Punch-Through (NPT) or IGBT3 modules, the Infineon FS75R12KE3G offers a significant leap in performance. Its primary advantage is the vastly improved trade-off between Vce(sat) and switching loss. While newer technologies like SiC may offer benefits at very high frequencies, the IGBT4 provides a more cost-effective and mature solution for the mainstream industrial frequency range. For applications requiring a robust, efficient, and easy-to-integrate 1200V/75A solution, this module represents a design sweet spot.
