1N5339BG from onsemi, in a DO-27. 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 | Cathode | passive | Cathode terminal, indicated by the polarity band; the 5.6 V zener (1N5339B) regulates at VZ 5.32 V min, 5.6 V nom, 5.88 V max at IZT = 220 mA. |
| 2 | Anode | passive | Anode terminal at the opposite axial lead from the polarity band; forward voltage is 1.2 V max at IF = 1.0 A. |
