Hi,

Umm, no, they're not, according to Nexperia:

"these dual are all 2 die solution where we take them from the same wafer.
No plans to develop these parts using a single die unfortunately since
the main goal is to maximize volumes of the single die version."

A shame as it would be a great option to replace the long-gone
2SC1583, etc.  I remember years ago asking Philips about the PUMX1 and
got a similar response:
