BZV55-B47 from Nexperia, in a MiniMELF. 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 package; the datasheet gives no pin-specific limits beyond the device ratings in Table 5. |
| 2 | anode | passive | Anode (the 'a' terminal of the graphic symbol, opposite the cathode); the datasheet gives no pin-specific limits beyond the device ratings in Table 5. |
