Technical Analysis for High-Power Systems

The standout characteristic of the FZ2400R17HP4_B2 is its nominal DC collector current (ICnom) of 2400 A, with a repetitive peak rating of 4800 A. This level of current handling allows system designers to maximize the power output per module, which can simplify the overall inverter architecture and reduce the need for complex module paralleling. This capability is based on Infineon’s robust Trench/Fieldstop IGBT4 technology, which offers a well-established balance between performance and ruggedness for industrial applications. Effective liquid cooling for megawatt converters is often essential to fully utilize this capacity.

Effective thermal management is fundamental to reliability in high-current modules. This device specifies a maximum operating junction temperature (Tvj op) of 150°C, providing significant thermal headroom for demanding load cycles. This is complemented by a low thermal resistance from junction-to-case (RthJC) of 0.009 K/W per IGBT. Think of thermal resistance as the narrowness of a pipe carrying heat away. The low RthJC value of this module acts like a very wide pipe, allowing waste heat to be transferred efficiently from the silicon chip to the heatsink. This performance is critical for maintaining system stability and longevity when operating under continuous high-current conditions.

Optimized Application Scenarios

The specifications of the FZ2400R17HP4_B2 are tailored for specific high-power industrial and renewable energy applications:

Engineer’s FAQ

How is the total junction-to-heatsink thermal resistance calculated for the FZ2400R17HP4_B2?
The datasheet provides the junction-to-case thermal resistance (RthJC) as 0.009 K/W per IGBT. To find the total thermal resistance to the heatsink (RthJH), you must add the thermal resistance of the case-to-heatsink interface (RthCH), which depends on the thermal interface material (TIM) used. The formula is: RthJH = RthJC + RthCH.
What are the specified mounting torque values for this module?
According to the datasheet, the recommended torque for the M8 mounting screws is 10 – 12 Nm. For the M8 main electrical terminals, the torque is also 10 – 12 Nm, and for the M4 auxiliary terminals, it is 1.2 – 1.5 Nm. Applying the correct torque is critical for ensuring low thermal resistance and reliable electrical connections. You can learn more about the importance of IGBT terminal torque.
What is the maximum continuous operating junction temperature?
The FZ2400R17HP4_B2 is rated for a continuous operating junction temperature (Tvj op) of up to 150°C. Operating within this limit requires an appropriately designed thermal management system capable of dissipating the generated heat effectively.
Can this IGBT module be used in a parallel configuration?
Yes, the module’s design is suitable for parallel operation. The IGBTs exhibit a positive temperature coefficient for VCEsat, which helps promote balanced current sharing between modules. However, for successful IGBT paralleling, a symmetrical mechanical and electrical layout of the busbars is essential to minimize stray inductance and ensure even current distribution during switching transients.
