BZD27C43P 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; the color band denotes the positive end, and the BZD27C43P has a Vz of 40 to 46 V at IZT = 10 mA. |
| 2 | A | passive | Anode of the zener diode; the datasheet gives a forward voltage of 1.2 V maximum at 0.2 A. |
