FB20R06W1E3: Technical Data for 600V PIM IGBT Module
Engineered for robust thermal performance and system reliability, the Infineon FB20R06W1E3 is a 600V, 20A PIM IGBT module integrating Trench/Fieldstop IGBT3 technology. Key Specifications: 600V VCES | 20A IC nom | Tvj max 175°C. Benefits include optimized switching losses and enhanced thermal stability. This module directly addresses the engineering need for compact, thermally efficient power stages by integrating a three-phase bridge, brake chopper, and NTC into a single EasyPIM™ housing, thereby simplifying thermal management through a unified heat sink interface.
Strategic Power Conversion in a Consolidating Market
The drive towards higher power density and simplified assembly in industrial automation places significant demands on power semiconductor modules. As system designers face pressures to reduce equipment footprints and bills of materials (BOM), integrated modules like the PIM (Power Integrated Module) architecture become critical. The Infineon FB20R06W1E3 exemplifies this trend by co-packaging a three-phase inverter, brake chopper, and rectifier stage. This high level of integration not only streamlines the manufacturing process but also enhances system reliability by minimizing interconnects and optimizing the thermal path from the silicon to the heat sink. Such consolidation is pivotal for creating cost-effective and dependable motor drives and auxiliary power units that meet modern industrial standards.
A Comparative Framework for Module Evaluation
When evaluating integrated power modules for motor drive applications, engineers must weigh several competing factors. The FB20R06W1E3 sets a specific benchmark with its combination of 600V Trench/Fieldstop IGBT3 technology and a comprehensive PIM configuration. For systems requiring a different voltage class or current handling, a component like the FS50R06W1E3 provides a similar integrated approach but with different power ratings. The selection process involves a detailed analysis of datasheet parameters to align the module's capabilities with the application's specific load profile and thermal budget. This data-driven approach ensures that the chosen module provides the necessary performance margin without over-engineering the solution.

Application Arenas Demanding Integrated Reliability
The integrated nature of the FB20R06W1E3 makes it a strong candidate for power conversion systems where space, assembly cost, and thermal management are primary design drivers. Its architecture is particularly well-suited for:
- Auxiliary Inverters: Providing reliable power for ancillary systems in larger industrial equipment, transportation, and commercial vehicles. The compact EasyPIM™ package simplifies integration into space-constrained enclosures.
- Motor Drives: Ideal for low-to-medium power variable frequency drives (VFDs), servo drives, and general-purpose motor controls. The integrated brake chopper is essential for managing regenerative energy in dynamic load applications. What is the benefit of its integrated NTC thermistor? It allows for direct monitoring of module temperature, a critical input for thermal protection algorithms.
- Air Conditioning Systems: The module's efficiency and compact design are valuable in commercial and residential HVAC compressor and fan controls, contributing to overall system energy savings.
For motor drives where thermal budget is a primary constraint, the FB20R06W1E3's Al2O3 substrate with low thermal resistance offers a distinct advantage over modules with less efficient thermal interfaces.
A Technical Dissection of the FB20R06W1E3
At its core, the FB20R06W1E3 leverages Infineon's Trench/Fieldstop IGBT3 technology, a mature platform known for its balance between conduction and switching losses. The module's design incorporates an Aluminum Oxide (Al2O3) substrate, which serves as an electrical insulator while providing a competent thermal pathway to the heatsink. This material choice is a key factor in the module's overall thermal resistance. The thermal resistance, Rth(j-c), can be compared to the width of a pipeline; a lower value signifies a wider pipe, allowing heat (the fluid) to be evacuated more effectively from the IGBT junction to the case, thus enabling higher operational reliability and longevity. The internal layout includes six IGBTs in a three-phase bridge configuration, a seventh IGBT for the brake chopper, and a full diode bridge rectifier, all within the EasyPIM™ housing. An integrated NTC thermistor provides a direct means for temperature sensing, facilitating crucial over-temperature protection mechanisms in the drive's control logic.
