1N5230BTR from onsemi, in a DO-35. 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, identified by the color band on the DO-35 glass case; the zener (1N5230B VZ 4.7V nominal at the test current) is reverse biased with the cathode positive. |
| 2 | A | passive | Anode, the axial lead opposite the color band on the DO-35 glass case. |
