Other Parts Discussed in Thread: ISO7842,
Has a partial dischargetest be done on this device? If so, could you share the report?

Hi Jerry,
Welcome to E2E! Partial discharge tests, like those required for IEC 60747-5-5, are a pass criteria for Isolation-related standards during qualification and production tests. In order for our devices to comply with quality and industrial standards, they all must pass partial discharge to help ensure their isolation barrier is intact.
Below is an excerpt from the "Maximum transient isolation voltage and isolation withstand voltage" section of High-voltage reinforced isolation: definitions and test methodologies, a reference document on our tests behind our isolators:
Please read Know your ISO: Understanding high-voltage isolation metrics and test capabilities and Enabling high voltage signal isolation quality and reliability for additional information on partial discharge tests. If you'd like details on isolation performance of TI devices, please visit http://www.ti.com/isolation/capacitive-isolation.html or feel free to reply.
Thank you,

I read document slyy063. The document speaks to the ISO7842. I need a document that states that the ISO7841 was submitted to the same test and meerts the same levels. Could you provide a conformation stating this?
Thanks
Hi Jerry,
ISO7842 and ISO7841 are made of the same technology, which is qualified and tested in production to the same voltage levels. Table 6.6 of the ISO7841 datasheet specifies Apparent charge, which is a result of partial discharge testing conducted following the process outlined in slyy063 for Viotm and Viorm.
Is this sufficient confirmation? Please let me know.
Thank you,
Manuel Chavez
