SMD marking code “Z12” — candidate parts
Small packages rarely print the full part number. The marking below maps to these part numbers — verify against the package, pin count and the manufacturer's datasheet before ordering.
Candidate part numbers
| Part number | Manufacturer | Package | Mapping basis | |
|---|---|---|---|---|
| BZT52C30 | MCC | SOD-123 | Public marking directory | |
| BZX84-C2V7 | PHI | SOT23 | Public marking directory | |
| MM5Z2V7 | ON* | SOD-523 | Public marking directory | |
| SSTJ212 | SILICONIX-VISHAY | SOT-23 | Public marking directory | |
| BZT52-C2V7T | — | SOD-523 | Public marking directory | |
| BZX84-C2V7-V | — | SOT-23 16dc - 3a,3g Phi | Public marking directory | |
| R1131N121D | — | SOT-23-5 | Public marking directory |
How these mappings are compiled: from public SMD marking directories and from our own stock records (marked Stock-record verified). We keep the original reference of every row internally so any mapping can be traced on request.
Markings are indicative only: the same code can denote different parts across manufacturers and packages. Always confirm with the physical batch marking and the original datasheet.
* Manufacturer derived from the part-number family (some directory entries carry no manufacturer) — treat it as a lead, not a datasheet fact.
