# BZX84C22_R1_00001

**PANJIT International** · Zener Diodes · SOT-23

BZX84C22_R1_00001 from PANJIT International, 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 single Zener diode (BZX84C22: 22V nominal Zener voltage, 20.9 to 23.1V at 5.0mA). |
| 2 | NC | unconnected | Not connected internally; the SINGLE pin diagram shows no connection to the diode. |
| 3 | K | passive | Cathode of the single Zener diode (410mW power dissipation, maximum reverse leakage 0.1uA at 15.4V for BZX84C22). |

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

- Symbol: `BZX84C22_R1_00001`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.92 mm, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). 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: `bzx84c22-r1-00001-etched.step` / `bzx84c22-r1-00001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84c22-r1-00001.step` / `bzx84c22-r1-00001.glb` are the bare package body.
