    Blown UB1

    Hello,

    I bought a UC300ETH-UB1 and I wanted to connect it to a 24V source, but unfortunately for my stupidity I connected the source badly and I destroyed the first fuse and also the TVS diode on UB1. Can anyone advise me where to get a new TVS2 diode? It says GEZ 7LH73 on it, but I can't find anything like that.

    Thank you in advance

    It's SMCJ24A, a 24V unidirectional TVS diode.
