I’m surprised that 119 without dedicated thermal pad is better than 219…

You can use the webplotdigitizer to check the total surface area between 119 and 219 package. But high performance non DTP MCPCB or non isolated MCPCB must be used.

Another improvement in 119/219D is its thermally more stable. From -30C to 25C the output remains almost the same. Less output reduction in higher temperature too.
