BZD27C15P 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 color band (positive end); for BZD27C15P zener voltage is 13.8 to 15.6 V at IZT = 50 mA. |
| 2 | A | passive | Anode; the datasheet shows only a cathode band on the SOD-123FL top view, with no printed pin numbers. |
