S12ZVL maximum supply voltage

What is the maximum supply voltage to S12ZVL?


I see that it is documented to be a 12V/18V nominal supply voltage. There is also a note in the reference manual that  "Operation in the range 20V<VSUP<26.5V is limited to 1 hour over lifetime of the
device. In this range the device continues to function but electrical parameters are degraded


I have an existing system with a 19.8V power supply. Can I use this to power the S12ZVL?

More particularly:

a) What happens if say I operate from a 23V power supply. Can I do this permanently if  I can accept "electrical parameters are degraded". (I am NOT using the S12ZVL for any analogue function)
