The FZ900R12KF5NOSA1 is a single IGBT module from Infineon Technologies, utilizing silicon technology and belonging to the TRENCHSTOP™ IGBT4 product family. It features a maximum collector-emitter voltage of 1200 V and a continuous collector current of 900 A at 25°C. The typical saturation voltage is 1.7 V, with a maximum operating temperature of +150°C and a minimum of -40°C. Packaged in a tray format, this component is designated as an End-of-Life (EOL) product by the manufacturer.
This specific part number is officially listed as End-of-Life (EOL) by Infineon Technologies. Distributors may report limited or restricted availability rather than standard active stock. Verification of current supply status through authorized channels is essential before design finalization due to the discontinued production status.
Engineers should evaluate alternative modules within the same voltage and current ratings that are currently in active production. Reviewing updated datasheets for newer generations ensures compatibility with modern gate drive requirements and improved thermal performance characteristics available in current Infineon portfolios.
The FZ900R12KF5NOSA1 belongs to the broader TRENCHSTOP™ IGBT4 family, which represents a mature generation of silicon power modules. This series was widely adopted for high-current industrial applications before being superseded by later technological iterations offering enhanced efficiency and switching capabilities.
Public documentation confirms the FF900R12IE4PBOSA1 as a functional substitute within the PrimePACK™ 2 housing. Other potential replacements include the FZ900R12KP4 and FZ900R12KE4, though mechanical dimensions and specific electrical parameters must be verified against the original design requirements.
