Technical Analysis of the FP100R12KT4
The primary value of the FP100R12KT4 lies in its high level of functional integration. By incorporating the input rectifier, brake, and inverter stages, it eliminates the need for multiple discrete components. This not only saves valuable board space but also simplifies the manufacturing process. A consolidated component count leads to fewer solder joints and potential points of failure, contributing to the overall reliability of the end system. For design teams, this integration simplifies procurement and inventory management.
A critical parameter for power modules is the collector-emitter saturation voltage (VCE(sat)), specified as a typical 1.75V for this device at 25°C. This value directly impacts conduction losses, which are a major source of heat generation. You can think of thermal resistance (RthJC) like the width of a pipe for heat to escape; the low junction-to-case thermal resistance of this module ensures efficient heat transfer to the heatsink. This efficiency, combined with the low VCE(sat), allows for smaller cooling systems or operation at higher ambient temperatures.
Optimized Application Scenarios
The specific feature set of the FP100R12KT4 makes it highly suitable for several key industrial applications.
- Variable Frequency Drives (VFDs): The complete rectifier-inverter-brake topology is the standard building block for VFDs, making this module a direct-fit solution.
- Servo Drives: The integrated brake chopper is essential for controlling motor deceleration in high-precision motion control systems.
- Uninterruptible Power Supplies (UPS): The module’s robust voltage rating and integrated rectifier and inverter stages are well-suited for the power conversion core of a UPS.
- Industrial Automation: Its compact EconoPIM™ 3 footprint and high integration level are ideal for space-constrained control cabinets.
This module is an optimal choice for motor control applications up to 30 kW where system integration and thermal efficiency are primary design goals.

Engineer’s FAQ for the FP100R12KT4
Q: How does the integrated NTC thermistor in the FP100R12KT4 improve system reliability?
A: The NTC thermistor provides a real-time temperature reading from the module’s baseplate. This allows the system’s controller to monitor thermal load, detect overheating conditions, and implement protective measures like power derating or shutdown, preventing catastrophic failure. This is a key element for mastering IGBT thermal design.
Q: What are the primary considerations for mounting the EconoPIM™ 3 package?
A: Proper mounting is critical for thermal performance. It requires a flat, clean heatsink surface and the correct application of thermal interface material (TIM) to minimize thermal resistance. The datasheet specifies the required mounting screw torque to ensure good thermal contact without causing mechanical stress to the module’s ceramic substrate.
Q: What is the benefit of the Trenchstop™ IGBT3 technology used in this module?
A: Trenchstop™ IGBT3 is a mature technology known for its balance between low conduction losses (low VCE(sat)) and switching losses. It offers high ruggedness and reliable performance, making it a standard for many industrial drive applications.
Q: Can this PIM module be used without the brake chopper?
A: Yes. If the application, such as a simple fan or pump controller, does not require dynamic braking, the brake chopper terminals can be left unconnected. The module will function as a standard rectifier and inverter pair.
