With this information designers could compare devices from different suppliers. Furthermore, the information indicates the devices limits. Datasheet values describe the devices behavior at different junction temperatures and testing conditions. The dynamic characterization tests, from which the switching losses are extracted, are related to a specific test setup with its individual characteristics. Therefore, these values can deviate from a final user application and between datasheets of older and newer products. The attached diagrams, tables and explanations refer to the IKW40N65H5 rev. 2.1 datasheet published in 2015-05-06 as an example. Table 3 and Table 4 only, refer respectively to IHW20N120R5 rev. 2.1 and IHW15N120E1 rev. 2.1. For the latest version of datasheets please refer to Infineons website www.infineon.com. Infineons IGBT datasheets are normally arranged to contain: A cover page with a short description of part number, IGBT technology and diode in case of DuoPack Summarized features, key parameters, applications as well as basic package information Maximum rated electrical values and IGBT thermal resistance as well as diodes in case of DuoPack Electrical characteristics at room temperature, both static and dynamic parameters Switching characteristics at 25C and 150 or 175C Electrical characteristics diagrams Package drawings Figures of definition for key parameters Revision history 1.1 Status of datasheets There are three different document types available. They correlate to the status of the product development. The datasheet types used are: Target datasheet, a document that contains values that are expected to be achieved. Values from these datasheets are commonly used for initial calculations and approximations. Nevertheless those information and values cannot be guaranteed for the final product thus the design of a power system should only rely on values from the final datasheet. Preliminary datasheet differentiating from a final datasheet in a way that certain data values are still missing, for example the maximum values. These missing values in the preliminary data sheet are marked to be defined (t.b.d). The preliminary datasheet is based on engineering samples, which are very close to final products. Normally the watermark of Draft exists on preliminary datasheets. Final datasheet including all the values, which are missing in the preliminary datasheet. Major changes of IGBT and diode characteristics or changes in datasheet values after the release of the final datasheet are accompanied by a Product Change Note (PCN).
