BZX85B180 from LGE, in a DO-41. 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 lead, identified by the color band at one end of the DO-41 molded body, which the datasheet states denotes the cathode end. |
| 2 | A | passive | Anode lead, at the end of the body opposite the cathode color band; the axial leads are solderable per MIL-STD-202 method 208. |
