[FAQ] Does TI perform outgassing testing on space grade devices (Space Enhanced Plastic (SEP) and QML Class P devices)?

Other Parts Discussed in Thread: TPS73801-SEP

What outgassing testing does TI perform on the space-grade plastic encapsulated parts,

  • TI performs the ASTM E595 testing process to ensure the material meets the Total Mass Loss (TML) and the Collected Volatile Condensable Materials (CVCM) requirements established by NASA and the European Space Agency (ESA).  During ASTM E595 testing, a material is placed in a thermal vacuum chamber and exposed to a 125°C  temperatures and vacuum force up to 5 x 10-5 torr. After a 24-hour outgas exposure, the test units are then weighed to determine mass loss, and the percentage of the volatile effluents that were collected during testing.


    For the -SEP devices, the test results of the ASTM E595 testing are documented Production Flow and Reliability Report for the respective device in the outgas test report section of the document. These documents are available in the “Technical Documentation” section of the respective product folders on For the MIL-PRF-38535 QML Class-P devices, the ASTM E595 testing is part of the QML Class-P flow.
