U5Z27 zener diode equivalent

[carbon]

I'm having problems finding details about a zener diode U5Z27, seems like they may have been discontinued. Anyone know of a suitable replacement?

It seems like it's now U5ZA27 - https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=u5za27&_sacat=0

27V 5W

Thanks very much, I'd found them but wasn't sure

I'm as sure as I can be without any more info. It's not an expensive part, at least

Its from a older truck electronic control unit and Ive found one mention of the diode on one forum but no mention of the replacement diode details, but as you say its not expensive and worth a try.

I think Ive now found the schematic for the pcb from a slightly newer version and the diodes are now shown as the U5ZA27 so looks like the correct parts. Thanks

Replacements arrived and have a different footprint but have managed to get them to fit, engine is running again so a success.
