ZMM5227BPF from ST Semtech, in a LL-34. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode, the end of the glass body marked with the cathode band; the zener (VZ) voltage is positive at this terminal relative to the anode. |
| 2 | A | passive | Anode, the unmarked end of the glass body. |
