FP10R12W1T4 Infineon 1200V 10A IGBT Module

Content last revised on August 28, 2026

Comprehensive Technical Overview of the FP10R12W1T4 PIM IGBT Module

Designed for high-efficiency low-power industrial drives, the FP10R12W1T4 integrates a full three-phase rectifier, brake chopper, and inverter stage. This module delivers a voltage rating of 1200V and a continuous DC collector current of 10A in a robust, compact package. By leveraging advanced semiconductor materials, it minimizes power dissipation with a total power rating of 105W. The integration of Infineon TRENCHSTOP™ IGBT4 technology reduces collector-emitter saturation voltage (VCE(sat)) to a typical 1.85V, which significantly lowers conduction and switching losses, mitigating the required heatsink footprint. For auxiliary drives prioritizing high power density in space-constrained enclosures, this 1200V 10A module is the optimal choice.

Application Scenarios & Value

Achieving High Efficiency and Thermal Headroom in Auxiliary Drives

Engineers often face the challenge of designing compact auxiliary motor drives and HVAC systems where physical space is extremely limited but thermal margins cannot be compromised. The FP10R12W1T4 addresses these constraints by consolidating a three-phase input rectifier bridge, a brake chopper, and a three-phase output inverter into a single EasyPIM module housing. This high level of integration eliminates the need for separate discrete components, reducing PCB routing complexity and cutting assembly costs. It serves as an essential building block for modern auxiliary inverters and small-scale industrial drives operating on three-phase grid systems.

In demanding environments like air conditioning compressor drives, start-up surge currents can induce rapid thermal spikes that threaten system reliability. The integrated Emitter Controlled 4 Diode inside the FP10R12W1T4 features a forward voltage characteristic of 1.75V at 10A, which helps stabilize forward voltage drop and prevent thermal runaway during sudden load fluctuations. By integrating these diodes directly alongside the IGBT chips, the module maintains tight electrical coupling and uniform thermal distribution, ensuring that transient overloads do not lead to localized hotspots or premature wear. While this unit is ideal for low-current applications, designers requiring higher power thresholds may consider the related FP15R12W1T4 for a 15A current capability, or the FP25R12W2T4 and FP35R12W2T4 to support up to 25A and 35A respectively.

Technical & Design Deep Dive

Analyzing the Trenchstop IGBT4 and Integrated PIM Topology for Reduced Switching Losses

At the core of this module is the Infineon TRENCHSTOP™ IGBT4 technology, which combines a trench gate structure with a field-stop structure. Think of the field-stop layer as a high-speed braking zone for charge carriers during turn-off; it quickly sweeps out stored carriers to minimize tail current, similar to how a high-performance disc brake halts a vehicle without pad fade. This architecture yields a turn-off energy loss (Eoff) of just 0.87 mJ at a junction temperature of 150°C and a collector current of 10A. By lowering switching losses, the module allows design engineers to run the system at higher carrier frequencies, which in turn reduces the size and cost of external filtering components.

By packaging the rectifier, chopper, and inverter stages under a single lid, the module behaves like a pre-engineered power substation on a postage stamp, cutting down copper busbar requirements and reducing parasitic stray inductance to a minimum. Furthermore, the integrated NTC thermistor acts as an internal thermometer, feeding real-time thermal data directly to the controller's gate drive circuit. This allows the system microcontroller to execute dynamic derating before the junction temperature reaches its absolute maximum limit of 175°C. This automated feedback loop removes the need for external temperature sensors mounted on the heatsink, streamlining system assembly and improving the precision of the over-temperature protection circuit. When decoding IGBT datasheets, paying attention to this integration is key. What is the primary benefit of the integrated NTC? It enables real-time thermal monitoring without external components. What packaging does the FP10R12W1T4 use? It is housed in a compact EasyPIM module.
