Are there any structural differences between IRS2110SPBF, IR2110STRPBF and IR25607 related to noise immunity?

※I know there is a structural difference between IRS2110S and IR2110S with and without clipping diodes.

Also, is there any difference in concept between IR (Gen2) and IRS (Gen5)?

 

Functional differences between A and B were referenced in the attached document.

You are probably asking about the critical topic "Transient spike immunity", when parasitic PCB layout at GND and VS pin affected IC. With very high parasitic inductance, it may easily kill the IC. There was a transition from IR to IRS maybe 18 years ago, it was declared as a pin-to-pin analog. Many customers started to change IR2110 to IRS2110 and faced failure...We investigated the case and found IRS has 100 times less transient immunity than IR! IRS can´t tolerate not perfect PCB layout and parasitic inductances. I have a picture dated 2002 from IR product (not IRS). So, technology is improving , now we have SOI (Silicon on Isolator) technology 2ED2110S06M  for example, much stronger than IR, and the  coreless technology, which is the best regarding transient immunity.
