Infineon FS35R12W1T4 | High-Efficiency EasyPIM™ Module for Compact Motor Drives
The Infineon FS35R12W1T4 is a highly integrated power module from the renowned EasyPIM™ 1B family, engineered to deliver exceptional performance in a compact footprint. This module combines a 1200V, 35A three-phase full-bridge inverter with a brake chopper and an NTC thermistor, providing a comprehensive solution for variable frequency drives, servo control systems, and other demanding power conversion applications. By leveraging Infineon's cutting-edge Trench Field Stop IGBT4 technology, the FS35R12W1T4 directly addresses the critical need for higher efficiency and simplified system design in modern industrial automation.
Technical Deep Dive: Where Efficiency Meets Reliability
- Trench Field Stop IGBT4 Technology: At the heart of the FS35R12W1T4 lies Infineon's 4th generation IGBT technology. This advanced design achieves an exceptionally low saturation voltage (Vce(sat)), which directly translates to reduced conduction losses. For engineers, this means less waste heat is generated during operation, allowing for smaller heatsinks, higher power density, and ultimately, a lower total cost of ownership through significant energy savings over the system's lifespan.
- Emitter Controlled 4 Diode: Paired with the IGBT4, the Emitter Controlled 4 fast-recovery diode is optimized for soft switching behavior. Its primary benefit is the minimization of voltage overshoots and high-frequency oscillations during turn-off. This inherent "softness" drastically reduces electromagnetic interference (EMI), simplifying the design and cost of external filtering components and helping your system meet stringent EMC standards with less effort.
Multi-Dimensional Application Value
The technical advantages of the Infineon FS35R12W1T4 translate into tangible benefits across a range of applications, solving specific industry pain points:
- Compact Motor Drives: For designers of modern AC motor drives, space is a premium. The all-in-one integration of the inverter, brake chopper, and temperature sensor within a single EasyPIM™ package significantly reduces PCB footprint and assembly complexity compared to discrete solutions. This enables the development of smaller, more powerful, and cost-effective drive systems.
- High-Performance Servo Control: The precision required in robotics and CNC machinery is non-negotiable. The fast, yet smooth, switching characteristics of the FS35R12W1T4 allow for highly accurate current control and rapid dynamic response, ensuring the precision and repeatability that high-performance servo systems demand.
- Uninterruptible Power Supplies (UPS): In critical power applications, efficiency is paramount. The module's low Vce(sat) minimizes energy loss during both battery charging and inversion states, which helps extend battery runtime and reduces the operational cooling costs of the UPS system.
- Industrial Automation & Machinery: Long-term reliability is the cornerstone of industrial equipment. The integrated NTC thermistor provides real-time temperature feedback, enabling precise thermal management and over-temperature protection. This proactive monitoring extends the operational life of the FS35R12W1T4 and the entire machine, reducing downtime and maintenance costs.
