Did you ever get a response? I've got a technical query with Nexperia and they haven't responded at all.
BTW "27" on these parts is usually Year-Month. Year is the last digit (so "2" is 2022, or in your case 2012) and the months are "123456789ond". Some of the other diode package datasheets detail the date marking, you just have to look around.
