Infineon FF100R12KS4 IGBT Module | Robust Performance for Demanding Drives
The Infineon FF100R12KS4 is a high-performance 1200V, 100A EconoPIM™ 2 module engineered for reliability and efficiency in demanding power conversion applications. As a cornerstone of modern industrial systems, this IGBT module integrates a three-phase inverter (six-pack) configuration into a compact, industry-standard package. It is specifically designed for designers of motor drives, uninterruptible power supplies (UPS), and general-purpose inverters who require a proven, cost-effective solution without compromising on thermal performance or electrical robustness. The FF100R12KS4 strikes a critical balance between low conduction losses and controlled switching behavior, making it a workhorse for systems operating up to the 22 kW power range.
Core Technology Breakdown: Efficiency Meets Reliability
IGBT4 Trench Field-Stop Technology
Technical Principle: At the heart of the FF100R12KS4 lies Infineon's mature and highly regarded IGBT4 Trench Field-Stop technology. This design creates a vertical trench gate structure that significantly lowers the on-state voltage drop (Vce(sat)). The integrated field-stop layer allows for a thinner N-base, reducing switching losses while maintaining excellent blocking voltage capability.
Application Value: For a system designer, this translates directly into reduced power dissipation. Lower Vce(sat) means less heat generated during conduction, especially critical in motor drive applications that experience high currents at low switching frequencies. This allows for smaller heatsinks, higher power density, and ultimately, lower system costs and enhanced reliability.
EconoPIM™ 2 Integrated Package Design
Technical Principle: The EconoPIM™ 2 package is not just a housing; it's an integrated solution. It co-packages the six IGBTs and six free-wheeling diodes of a B6 inverter bridge into a single module with an optimized internal layout. This design minimizes stray inductance and ensures symmetrical current sharing between parallel chips.
Application Value: This integration dramatically simplifies the power stage design and assembly process. Engineers benefit from a pre-tested, validated subsystem, reducing design cycles and potential points of failure. The low internal inductance of the FF100R12KS4 package helps to minimize voltage overshoots during switching, simplifying EMC filter design and improving overall system stability.
Application Showcase: Where the FF100R12KS4 Excels
- Industrial Motor Drives: In variable frequency drives (VFDs), the module's low conduction losses are paramount for maintaining high efficiency during high-torque, low-speed operation. Its robustness ensures it can withstand the demanding load cycles typical in industrial automation.
- Servo Drives: The controlled switching characteristics of the IGBT4 technology within the FF100R12KS4 provide the smooth and precise current control necessary for high-performance servo applications, enabling accurate positioning and dynamic response.
- Uninterruptible Power Supplies (UPS): For online UPS systems, efficiency is key to reducing operating costs. The FF100R12KS4’s excellent thermal performance ensures long-term reliability, a critical requirement for backup power systems that must be ready 24/7.
- Welding Equipment: Welding applications subject components to high-current pulses. This module's robust design and excellent thermal cycling capability make it a reliable choice for modern inverter-based welding power sources. This is a core component in our portfolio of IGBT modules for industrial use.

Frequently Asked Design Questions
- What is the ideal switching frequency for the FF100R12KS4?
The Infineon FF100R12KS4, based on IGBT4 technology, is optimized for applications with switching frequencies typically below 15 kHz. Its primary strength is low conduction loss, making it highly efficient in motor drives and UPS systems that operate in the 4 kHz to 12 kHz range. Pushing it to higher frequencies will result in increased switching losses, potentially requiring more substantial thermal management.
- How does this module compare to a similar module with newer IGBT7 technology?
IGBT7 technology is designed for lower switching losses at higher frequencies, making it ideal for fast-switching applications like high-frequency solar inverters or EV chargers. However, the FF100R12KS4 (IGBT4) often exhibits lower conduction losses (Vce(sat)), making it the more efficient and cost-effective choice for standard-frequency motor drives where conduction periods are long and switching events are less frequent.
