Can it be replaced directly?
There are several potential alternatives for BSD5C051V in the same SOD-523 package, but a direct drop-in replacement depends on matching the polarity (unidirectional or bidirectional), which must be verified.
Best replacement path
First, verify the target's polarity from its datasheet. If unidirectional, ESD5Z5V0 is a strong option. If bidirectional, H5VUD5BB or H5VND5B are good upgrade paths.
Main risk
Polarity mismatch is the main risk. Using a unidirectional diode where a bidirectional one is needed (or vice-versa) will lead to circuit failure or lack of protection.
