THS3111: Die Attach (Epoxy) voltage rating

Part Number: THS3111

Hi Team,

Our datasheet says THS3111 thermal pad is not electrically connected to die, customer wants to understand the voltage rating of Epoxy. I think they are talking about thermal pad voltage rating spec. Any insight about this?

Thanks.

  • Hi Andrew,

    I am not completely clear on their request for voltage ratings on the Epoxy.
    I believe they are trying to build a multi layer board and trying to pass a signal in a lower level from underneath the device. I want to say that because the thermal pad is not connected to the die that shouldn't be a problem however, you cannot 100% trust the isolation characteristics of epoxy. So, it's heavily recommended to clear the area in all layers!

    Here is an E2E post that this question occurred previously in as well:
    e2e.ti.com/.../2708440

    Overall, as long as the voltages aren't too high there shouldn't be a problem but we don't spec or guarantee this performance of the epoxy.

    Thanks!
