BZD27C27P 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 (color band denotes positive end); for BZD27C27P zener voltage is 25.1 V min to 28.9 V max at the test current of 25 mA. |
| 2 | A | passive | Anode; the datasheet shows only a cathode band on the SOD-123FL package, with no pin numbers printed. |
