Application Scenarios & Value
Achieving System-Level Benefits in High-Voltage Renewable Systems
In the field of industrial drives and Solar Inverter design, the FS225R17OE4 addresses the challenge of managing high-voltage transients while maintaining efficiency. For instance, in Wind Turbine pitch control systems, the module handles the surge currents required for rapid motor acceleration. The 1700V rating provides a necessary safety margin for systems operating on 690V lines, mitigating the risk of failure due to cosmic radiation and over-voltage spikes.
The engineering value is particularly evident in the EconoPACK™+ package’s ability to manage heat. Consider Thermal Resistance (Rth(j-c)) as a thermal highway: a lower value, like the 0.10 K/W found here, acts like a wide, multi-lane road that allows heat to escape from the silicon junction to the heatsink with minimal resistance. This directly facilitates higher power density without exceeding the 150°C operational junction temperature.
For systems demanding even greater throughput, the FS450R17KE3 offers a higher current capability while maintaining the 1700V standard. Understanding these nuances is critical for balancing voltage integration and power density in complex layouts.
Technical Deep Dive
A Closer Look at Trenchstop IGBT4 Integration and Thermal Stability
The FS225R17OE4 utilizes TRENCHSTOP™ IGBT4 technology, which is optimized specifically for low switching losses (Eoff/Eon) compared to previous generations. This optimization is vital for Variable Frequency Drive (VFD) applications where the carrier frequency typically ranges from 2kHz to 8kHz. By reducing the energy lost during each switch transition, the module allows for smaller, more cost-effective cooling systems.
Another critical design element is the Emitter Controlled 4 diode, which is paired with the IGBT. This diode features a soft recovery characteristic, which significantly reduces electromagnetic interference (EMI) during high-speed switching. For engineers, this means less time spent on Snubber Circuit design and filtering.
When evaluating long-term reliability, it is essential to consider Power Cycling Capability. The FS225R17OE4 is designed to withstand frequent temperature swings, common in heavy industrial cycles.

Technical FAQ
How does the Vce(sat) of 2.00V impact the efficiency of a 100kW inverter?
The Vce(sat) represents the conduction loss of the module. A typ. value of 2.00V at 225A ensures that static losses remain low during the "on" state. In a 100kW system, even a small reduction in Vce(sat) can result in significant energy savings and reduced heat dissipation requirements over time.
What is the importance of the 1700V rating in 690V AC applications?
Standard 1200V modules do not provide sufficient headroom for the DC link voltages associated with 690V AC systems (which can reach ~1100V DC). The 1700V rating of the FS225R17OE4 ensures the device operates safely within the Safe Operating Area (SOA) even during transient spikes.
Does the FS225R17OE4 require a negative gate voltage for turn-off?
While TRENCHSTOP™ IGBT4 is robust, applying a Negative Gate Voltage (e.g., -15V) during the off-state is a recommended industry practice to prevent parasitic turn-on caused by the Miller effect, especially in high dV/dt environments.
Can the integrated NTC thermistor be used for primary safety shutdown?
The internal NTC is highly accurate for monitoring the baseplate temperature. However, due to the thermal lag between the silicon junction and the NTC, it should be used for steady-state thermal management, while Short-Circuit Withstand Time (10μs for this module) and fast over-current detection circuits handle transient faults.
Strategic implementation of the FS225R17OE4 requires an integrated view of electrical protection and Thermal Management. As industrial systems move toward higher efficiency and smaller footprints, the ability of this IGBT Module to deliver 225A at 1700V with reliable thermal feedback positions it as a foundational component for next-generation power architecture. Ensuring your Gate Drive design aligns with Infineon recommendations will maximize the module's Safe Operating Area and operational lifespan.
