Default Zener Diode Identification

Ive got a shorted zener diode on a power board for a sub but struggling to make sense of the markings to identify a replacement.

From what i can make out says 33B5T

This is what a google brings up

https://datasheetspdf.com/pdf/102878...ents/MZC33B5/1

Was looking at this as a replacement 3.3v Is this suitable?

It’s just a wireless sub part of a LG sound bar setup


LG nb3530a

Actually found another shorted zener directly after a octocupler from the primary to secondary side.

I’ll get some board pics up shortly

And yes the 5 could be a S, so 33BST

I’ve just bought a kit of Amazon which includes loads of values
