CSD19532Q5B: Maximum value of Trr

Higa,
Normally, for parameters that we do not test in production, we just recommend adding 30% to the typical value to get the max.

However, I would strongly caution against that in this case, because Trr (and the associated reverse recovery charge, Qrr) are extremely dependent on the board, driver strength, and other conditions they are measured at.

I wrote a whole blog about it here: e2e.ti.com/.../understanding-mosfet-data-sheets-part-5-switching-parameters

And made a video about it here: training.ti.com/understanding-mosfet-datasheets-switching-parameters

Basically, we can't guarantee any max value for Trr unless you were able to exactly replicate the conditions it was measured at. But for those specific conditions listed in the datasheet, multiplying by 1.3 to add 30% is probably as close to an accurate safeguard as you can get, to account for part to part variation.
