BZV85-C33 from Nexperia, 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, identified by the marking band on the glass body, which indicates the cathode. |
| 2 | anode | passive | Anode, the terminal opposite the cathode marking band on this 2-lead axial glass package. |
