Identify BM 64 diodes (SMD)
They are Vishay SMBJ15CA bidirectional TVS diodes.
The logo is frequently used on Vishay didoes, hence the manufacturer decision. The image below is a generic image of such a diode to Vishay showing the logo they use.
The package size matches, SMB (DO-214AA), at 4.3mm long x 3.5mm wide, with wrap-under leads.
The marking is BM, not MB. Which indicates a 15V bidirectional variant from their SMBJ series.
The 64 will be a date code.

The lack of a cathode marking band is due to the fact that it is a bidirectional TVS diode (two diodes in anti-series - cathode to cathode internally), and so will not have the cathode marker per the notes.
Furthermore, the Z digit again per the notes is optional. Yours doesn't have it, but it has the XY correctly positioned to the left of the package.
