Infineon EVM31-060 | The Engineer's Choice for High-Reliability 600V Power Conversion
The Infineon EVM31-060 is a 600V, 50A IGBT module engineered for power systems that demand a balance of rugged reliability and exceptional efficiency. Integrating a full three-phase inverter bridge, this Power Integrated Module (PIM) simplifies system design, reduces component count, and accelerates time-to-market for a wide range of industrial applications. It is not just a component; it's a foundational block for robust and cost-effective power electronics.
Technical Deep Dive: Where Performance Meets Reliability
The performance of the EVM31-060 is rooted in two core Infineon technologies. Understanding them reveals why this module consistently outperforms standard solutions in demanding environments.
- Trench Gate Field-Stop (FS) IGBT Technology: This isn't just another IGBT structure. The Trench Gate architecture creates a vertical current path, significantly reducing the on-state voltage drop (VCE(sat)). The Field-Stop layer, placed strategically within the silicon, truncates the electric field during the off-state, which enables a much thinner N-drift region. The direct engineering benefit is a dramatic reduction in both conduction and switching losses. This dual-pronged efficiency boost means lower operating temperatures, smaller heatsinks, and ultimately, a more compact and reliable end product.
- Integrated Emitter-Controlled Diode: The co-packaged freewheeling diode is performance-matched to the IGBT. It features a soft, yet fast, reverse recovery characteristic. This is critical for minimizing voltage overshoots and oscillations during commutation, particularly in hard-switched applications like motor drives. By mitigating these electromagnetic interference (EMI) sources at the chip level, the EVM31-060 simplifies the design of external snubber circuits and reduces the overall system's EMI signature.
Application Scenarios & Value Proposition
The Infineon EVM31-060 is specifically tailored to excel where efficiency and durability are paramount. Its design provides tangible advantages across several key applications:
- Variable Frequency Drives (VFDs): In motor control, the low VCE(sat) directly translates to reduced heat generation within the drive cabinet, enhancing the longevity of all surrounding components. The module's robust Short-Circuit Safe Operating Area (SCSOA) provides critical protection against motor winding faults, preventing catastrophic system failure.
- Solar Inverters: For grid-tied solar applications, every fraction of a percent in efficiency counts. The EVM31-060’s optimized balance of low conduction and switching losses maximizes energy harvest across a wide range of operating conditions, from early morning to peak sun. This focus on efficiency is central to modern high-efficiency power systems.
- Uninterruptible Power Supplies (UPS): Reliability is the non-negotiable metric for UPS systems. The high thermal cycling capability and integrated design of the Infineon EVM31-060 ensure dependable operation during critical power transitions, providing the confidence needed for mission-critical loads.

Selection Guidance: EVM31-060 vs. Higher-Frequency Modules
Choosing the right IGBT module is a critical design decision. The EVM31-060 is optimized for applications operating in the 5 kHz to 20 kHz range, such as standard motor drives and UPS systems. In this band, its Field-Stop technology provides an unbeatable combination of low conduction losses and robust performance.
However, for applications requiring higher switching frequencies (>20 kHz), such as high-power-density SMPS or welding equipment, an alternative module featuring faster switching characteristics might be more suitable. While a faster module reduces switching losses, it often comes at the cost of higher VCE(sat) (conduction losses). The EVM31-060 represents the ideal choice for mainstream industrial applications where overall system efficiency and ruggedness are the primary design drivers. Understanding the trade-offs between switching frequency and on-state losses is crucial, a topic further explored in our guide to IGBT selection for high-frequency designs.
Frequently Asked Questions (FAQ)
1. What are the best practices for thermal management with the EVM31-060?Effective thermal management is key to unlocking the module's full potential. Due to its low VCE(sat) and optimized diode, thermal dissipation requirements are reduced. However, we recommend using a high-quality thermal interface material (TIM) with low thermal resistance and ensuring a flat, clean heatsink surface. Proper mounting torque as specified in the datasheet is critical to minimize the thermal resistance from case to heatsink (Rth(c-h)).
2. Can the EVM31-060 be paralleled for higher current applications?While this module is a highly integrated PIM, paralleling entire modules is an advanced technique. The EVM31-060 exhibits a positive temperature coefficient for VCE(sat), which aids in thermal balancing between parallel devices. However, achieving proper current sharing requires meticulous attention to gate drive symmetry and power layout parasitics to ensure balanced dynamic performance. For applications requiring significantly higher current, consider a single module from a higher power class, like the Infineon PrimePACK™ series.
