2SC0108 - dv/dt definition

Posted by: mf_123 on

On the datasheet for the core drive (above) there is a definition of the dv/dt maximum:

Anyone know how this has been measured and what the dV value is for this dV/dt ? 

What is the definition of dV/dt in this case ? Is it over a defined period of the waveform or the steepest slope ?

Dear
This parameter shows the capability of the target driver to withstand common mode noise during driver operation.
the dV is the voltage difference from the secondary side to the primary side , the dt is the period of time.

Thank you for the response, and confirming what dv/dt indicates.

I was more interested to know how this dV/dt is defined ? In other words do PI apply a constant linear dV/dt across the full operating voltage of the device , or, do they define the maximum by the steepest applied dV/dt across the device which may only be applied over a very small dV

Dear
The key point here is why dv/dt is mentioned as a parameter for a gate driver.
In fact, the current which is generated by the target dv/dt is the one that could lead to a problem.
