**onsemi** · Voltage References · SOT-23

BZX84B6V8LT1G from onsemi, 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 | Anode | passive | Anode of the Zener diode; the Zener breakdown (VZ 6.66 V min to 6.94 V max at IZT = 5 mA) is reverse-biased with respect to this pin. |
| 2 | NC | unconnected | No connection. |
| 3 | Cathode | passive | Cathode of the Zener diode, indicated by the polarity band; goes positive relative to the anode in Zener regulation. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `BZX84B6V8LT1G`
- 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, 1.0 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)
- 3D model files: `bzx84b6v8lt1g-etched.step` / `bzx84b6v8lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84b6v8lt1g.step` / `bzx84b6v8lt1g.glb` are the bare package body.
