Hi,
I havea diode looking exact like this one but with CS writing instead of BW. I think it's Taiwan semiconductors. Any suggestions what to replace it with ?

No, a diode that appears that size in a photo is hard to estimate the actual wattage and reverse current and speed. How did you diagnose that this diode was the issue?

The diode blew (you could not identify it) and I found a PCB in a another device which looked identical to mine so I took these photos.

 

Some code books show the BW as a 33V 0.3W Zener diode (BZX399C33). I don't see a similar reference for "CS", sorry.
That said, you could measure the voltage across a working unit to verify it is indeed a zener diode. If your blown diode is the CS one, not much help here...
Otherwise, this is just a guess, many SMD codes are not 100% accurate.

 

That could be good guess. To add some context. This diode is on a PCB used to control a table with 2 motors. They run at 24v but there is also some 5v logic however this diode I think is used for the 24v part. I added some photos of the PCB.
