BZV85-C4V7 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; the datasheet marks the band as the cathode indicator for the BZV85 series, including BZV85-C4V7. |
| 2 | anode | passive | Anode, the terminal opposite the marking band; forward current is limited to a maximum of 500 mA for the device (IF, Table 5). |
