Infineon FP40R12KT3 PIM Module | Compact Power Integration with TRENCHSTOP™ IGBT3
The Infineon FP40R12KT3 is a highly integrated Power Integrated Module (PIM) designed to streamline the development of compact and efficient power conversion systems. Leveraging Infineon's proven TRENCHSTOP™ IGBT3 technology, this module combines a three-phase inverter, a brake chopper, and a rectifier bridge into a single, thermally efficient EconoPACK™ 2 package. It is an ideal solution for engineers seeking to reduce system complexity, minimize assembly time, and enhance reliability in mid-power applications.
Technical Deep Dive: Core Advantages of the FP40R12KT3
The Power of All-in-One Integration (PIM)
Unlike discrete component designs that require separate rectifier, brake, and inverter stages, the FP40R12KT3 consolidates these functions into one housing. This PIM architecture delivers tangible engineering benefits. It drastically reduces the number of components, simplifies the PCB layout, and minimizes parasitic inductance between stages. The result is a more compact final product with improved electromagnetic compatibility (EMC) performance and a significantly shorter time-to-market.

Balanced Performance with TRENCHSTOP™ IGBT3
At the heart of this module is Infineon's TRENCHSTOP™ IGBT3 technology. This generation strikes an optimal balance between conduction and switching losses. It features a low collector-emitter saturation voltage (VCE(sat)), which directly translates to lower power dissipation during operation. This reduces the demands on your cooling system, allowing for smaller heatsinks and potentially lower overall system cost. It’s a workhorse technology, valued for its robustness and cost-effectiveness in applications where extreme switching frequencies are not the primary design driver.

Application Scenarios and Value Proposition
- General Purpose Motor Drives: The PIM configuration simplifies the front-end and motor control stages of a Variable Frequency Drive (VFD). The integrated brake chopper is particularly valuable for handling regenerative energy during motor deceleration, enhancing system safety and control without requiring external braking units.
- Servo Drives: In precision motion control, the FP40R12KT3's balanced performance ensures reliable torque and speed regulation. The low parasitic inductance of the integrated package contributes to cleaner switching waveforms, improving control accuracy.
- Uninterruptible Power Supply (UPS): This module provides a complete power conversion block for small to medium-sized UPS systems. The integrated three-phase rectifier and inverter simplify the design of the main AC-DC-AC power path, while the brake chopper can manage the battery charging/discharging circuit.
- Industrial Automation & Robotics: For multi-axis robots or automated machinery, the compact footprint of the Infineon FP40R12KT3 allows for decentralized drive designs, placing the power electronics closer to the motor and reducing cabling complexity.
Selection Guidance: FP40R12KT3 vs. Alternatives
When selecting a power module, it's crucial to match the technology to the application's needs. The FP40R12KT3, with its IGBT3 technology, is an excellent choice for applications operating in the low-to-moderate switching frequency range (typically 15-20 kHz), you might consider modules based on newer technologies like Infineon's IGBT4 or IGBT5, which are optimized for lower switching losses. However, for cost-sensitive projects where ruggedness and integration are key, the FP40R12KT3 remains a superior and highly practical choice.
