BZX84B5V1-E3-08 from Vishay Intertech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the Zener diode, shown connected to the diode symbol in the circuit drawing. |
| 2 | NC | unconnected | Pin 2 is drawn with no connection to the Zener diode in the circuit configuration drawing (single diode). |
| 3 | K | passive | Cathode of the Zener diode, shown connected to the diode bar in the circuit drawing. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
BZX84B5V1-E3-08 - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.01 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
