Infineon FF300R12KE3 | High-Efficiency 1200V IGBT for Demanding Inverter Applications
The Infineon FF300R12KE3 is an industry-benchmark 1200V, 300A six-pack IGBT module designed for high-power, high-frequency power conversion systems. Housed in the robust EconoPACK™ 3 package, this module integrates Infineon's advanced IGBT4 Trench Field-Stop technology to deliver a superior balance of low power losses and high operational reliability. It's an ideal solution for engineers developing industrial motor drives, uninterruptible power supplies (UPS), and renewable energy inverters where efficiency and thermal performance are non-negotiable.
Technical Deep Dive: The Core of Performance
The excellence of the FF300R12KE3 lies in its meticulously engineered silicon. Two key technologies set it apart:
- IGBT4 Trench and Field-Stop Technology: This isn't just an incremental update; it's a fundamental architectural advantage. The trench-gate structure significantly reduces the collector-emitter saturation voltage (Vce(sat)), directly translating to lower conduction losses. The integrated field-stop layer allows for a thinner n-base, which minimizes switching losses, especially at higher frequencies. For system designers, this means less waste heat, smaller heatsinks, and a more compact, cost-effective overall design.
- Emcon High-Efficiency Diode: Paired with each IGBT is a high-efficiency freewheeling diode. Engineered for soft recovery characteristics, this diode minimizes voltage overshoots and oscillations during turn-off. This "softer" switching behavior is crucial for simplifying EMI filter design and ensuring compliance with stringent EMC standards, saving valuable design and testing time.
Diverse Applications, Tangible Benefits
The FF300R12KE3 isn't just a component; it's a problem-solver across various high-power applications:
- Industrial Motor Drives: In applications like VFDs and servo drives, precise control and efficiency are paramount. The module's fast and soft switching enables higher PWM frequencies, leading to smoother motor operation, reduced audible noise, and lower torque ripple. This results in better process control and enhanced system precision. Explore our full range of IGBT Modules for your specific drive requirements.
- Solar & Wind Inverters: Maximizing energy harvest is the primary goal. The low overall power losses of the Infineon IGBT4 technology in the FF300R12KE3 boost the inverter's conversion efficiency, translating directly to a higher energy yield (kWh) and faster return on investment for the end-user.
- Uninterruptible Power Supplies (UPS): Reliability is critical. The module's robust design and integrated NTC thermistor for real-time temperature monitoring ensure stable operation under heavy load and overload conditions. Its high efficiency also reduces operating costs by minimizing standby power consumption.

Selection Advice: Six-Pack vs. CIB Modules
Engineers often weigh the FF300R12KE3 (a six-pack module) against Converter-Inverter-Brake (CIB) modules. While CIBs offer higher integration by including the input rectifier and brake chopper, the FF300R12KE3 provides greater design flexibility. This modular approach is superior for applications requiring a customized front-end rectifier (e.g., active front end) or a more powerful, separately-managed braking circuit. If your system requires a standard, all-in-one solution for a simple IGBT in motor drive application, a CIB might be suitable. However, for higher performance, custom topologies, or optimized thermal management, the FF300R12KE3 offers a more robust and adaptable foundation.
Frequently Asked Questions
- Can the FF300R12KE3 modules be paralleled for higher current?Yes, paralleling is possible. Due to the positive temperature coefficient of Vce(sat) in IGBT4 technology, the modules share current effectively. However, careful attention must be paid to symmetrical PCB layout and gate drive design to minimize stray inductance and ensure simultaneous switching.
- What is the purpose of the integrated NTC thermistor?The NTC thermistor provides a direct, real-time temperature reading of the module's baseplate. This feedback is critical for the control system to implement over-temperature protection (OTP), preventing thermal runaway and significantly enhancing the long-term reliability of the power system.
