FF1400R12IP4 High-Power IGBT Module – The “Heart” of Industrial Power Conversion

FF1400R12IP4 Product Overview: A Decade of Proven Industry Standard

The FF1400R12IP4 is a high-power IGBT module from Infineon’s PrimePACK™3 series. It features a 1200V/1400A rating, integrating TrenchStop™ IGBT4 chips and 4th generation emitter-controlled diodes, with a built-in NTC temperature sensor — a highly integrated power semiconductor solution. Since its launch in 2014, the module has become the gold standard in demanding applications such as European wind power, high-speed rail traction, and high-power charging stations, thanks to its exceptional reliability. This is not a new product chasing “impressive specs”; it is an industry benchmark forged by ten years of field validation and reliability. It doesn’t just evolve — it sets the standard.

FF1400R12IP4 Key Technical Specifications

FF1400R12IP4 Core Technical Advantages

Low Switching Loss, High Efficiency

TrenchStop/Fieldstop IGBT4 technology combines trench gate and field stop structures to minimize both static and dynamic losses. Compared with previous generations, turn-on/turn-off times and switching energies are significantly reduced, improving overall system efficiency.

High Short-Circuit Ruggedness

Self-limiting short-circuit current design protects the chip from damage even under extreme conditions. Unmatched robustness ensures stable operation under high current surges.

Accurate Temperature Monitoring & Smart Protection

Built-in NTC temperature sensor enables real-time junction temperature monitoring. When temperature exceeds safe limits, the system can automatically derate or trigger protection, effectively extending equipment life.

High Insulation Strength, Safe & Reliable

4kV AC insulation rating for 1 minute, packaging material CTI > 400, large creepage distances and clearances — safe operation even in high-pollution environments.

Positive Temperature Coefficient of VCEsat for Easy Paralleling

The positive temperature coefficient of saturation voltage enables automatic current sharing when multiple modules are paralleled, simplifying design and debugging.

RoHS Compliant & Environmentally Friendly

Meets RoHS requirements, lead-free design, complies with major global environmental regulations.
