1N5341BRLG 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, indicated by the polarity band; the primary path of heat conduction is through the cathode lead, and the zener is reverse-biased with this pin positive. |
| 2 | Anode | passive | Anode terminal at the opposite end of the axial body from the polarity band. |
