BZD27C120P from LGE, in a SOD-123FL. 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, marked by the cathode band on the SOD-123FL package; the color band denotes the positive end (cathode) and the part is unidirectional, with Vz 114-127 V at 0.65 mA test current region per datasheet table (IZT 5 mA). |
| 2 | A | passive | Anode of the zener/protection diode on the SOD-123FL package, the terminal opposite the cathode band. |
