The document has a graph of (Figure 9 Time evolution of PBTI at 200°C using a stress bias of +25 V.), but does this also occur when the temperature is below 100°C, etc.?

Please provide a graph of temperature-dependent characteristics, if any.


Also, how much do gate threshold voltage and ON resistance change with DC BTI?

Hi, @Dipti_Kiran ,

As a system, we have a need to make the FETs always ON in standby mode.

In this case, there is a concern that applying a DC bias to the gate may cause DC BTI, which changes the threshold voltage and ON resistance.

Hi @AkUm ,

I will request you to create a case under “Product qualification” under "Sales Support" track in the Mycases portal. Please find the attached leaflet, it will guide you to create a case.

Please let me know, if you need any help in case creation.

Regards,

Dipti
