Zener diodes replacements

[turboyam]

I have to replace 2 different zeners on an amp board and, replacements are hard to find. The originals were: WZ-280 and WZ-197
Found NTE5034A and NTE5029A but even those are hard to find!.
I always get stuff from Digikey Canada but, they have nothing like these in stock.
Any ideas???

The 1N4750 Zener is 27V 1/2W and will be fine instead, well within the 5% of 28V.

The 1N4747 Zener is 20V 1/2W and will be fine.

Connect two or more zener diodes in series.

If you click them Digikey page opens and shows content.

I GUESS they don´t want to "come" to an external site but have no problem with letting you "go there"

Seen same on many places 🙄
