Infineon FP100R12KT4 IGBT Module | Robust TRENCHSTOP™ IGBT4 for High-Reliability Drives
The Infineon FP100R12KT4 is a high-performance Power Integrated Module (PIM) designed for demanding power conversion applications. Housed in the industry-proven EconoPACK™ 2 package, this 1200V, 100A module integrates a three-phase inverter with a brake chopper and a rectifier bridge. It is engineered to deliver a balanced combination of conduction and switching performance, making it an ideal workhorse for industrial motor drives, uninterruptible power supplies (UPS), and commercial HVAC systems where reliability and efficiency are non-negotiable.
Technical Deep Dive: The Core of Performance
The value of the Infineon FP100R12KT4 lies in its meticulously engineered components that address common design challenges in power electronics. Two features stand out:
- TRENCHSTOP™ IGBT4 Technology: This isn't just another IGBT. The IGBT4 represents an optimized balance between low saturation voltage (VCE(sat)) and minimal switching losses.
Application Value: For a system designer, this means greater flexibility. In lower frequency applications like motor control, the low Vce(sat) directly translates to reduced conduction losses and less heat generation, allowing for smaller heatsinks and a more compact system design. In higher frequency applications, the controlled switching behavior helps manage electromagnetic interference (EMI) without sacrificing overall efficiency.
- Integrated NTC Thermistor & EconoPACK™ Package: System reliability is paramount. The module includes an integrated NTC thermistor for precise, real-time temperature monitoring. This provides a critical feedback loop for the control system to prevent thermal runaway. This is coupled with the robust EconoPACK™ 2 housing, known for its excellent thermal cycling capability and straightforward press-fit pin assembly.
Application Value: This integration simplifies system design by eliminating the need for external temperature sensors. It enhances operational safety and extends the lifespan of the entire power system by ensuring the module operates within its Safe Operating Area (SOA).

Solving Real-World Problems Across Applications
- Variable Frequency Drives (VFDs): In VFDs, frequent start/stop cycles and varying loads create significant thermal stress. The FP100R12KT4's robust thermal management and efficient TRENCHSTOP™ IGBT4 technology ensure stable performance, reducing energy consumption and preventing nuisance trips.
- Uninterruptible Power Supplies (UPS): For a data center or hospital, UPS failure is not an option. The module's proven reliability and integrated thermal monitoring provide the assurance needed for these critical systems, ensuring seamless power conversion when it matters most.
- Servo Drives: Precision and fast response are key in robotics and CNC machining. The module's low inductance design and fast-switching diodes enable the crisp, accurate control required for high-performance servo drives.

Comparative Insight: FP100R12KT4 vs. Newer Generations
When selecting a power module, it's crucial to compare it with alternatives. For instance, while a newer Infineon TRENCHSTOP™ IGBT7 module might offer lower switching losses for very high-frequency designs, the FP100R12KT4 provides a highly cost-effective and proven solution for applications operating in the typical motor drive frequency range (2-16 kHz). Its robustness and extensive field deployment make it a lower-risk choice for established industrial platforms where reliability and total cost of ownership are prioritized over cutting-edge performance at any cost.

Frequently Asked Questions (FAQ)
- Can this module be used in parallel for higher power output?
Yes, but careful design is essential. Paralleling requires closely matched VCE(sat) characteristics and a symmetrical gate drive layout to ensure proper current sharing and prevent oscillations.
- What is the primary advantage of the included brake chopper?
The integrated brake chopper is crucial for motor drive applications. It provides a path to dissipate regenerative energy when the motor is decelerating, protecting the DC link from overvoltage and enhancing system safety.
