# BZX84C15_R1_00001

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

BZX84C15_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; for BZX84C15 the nominal Zener voltage is 15 V (14.25 to 15.75 V) at IZT = 5.0 mA. |
| 2 | NC | unconnected | Not connected internally; the SINGLE package diagram shows no connection to the diode. |
| 3 | K | passive | Cathode of the single Zener diode, which is the Zener-voltage terminal; maximum power dissipation is 410 mW at 25°C. |

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

- Symbol: `BZX84C15_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: `bzx84c15-r1-00001-etched.step` / `bzx84c15-r1-00001-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bzx84c15-r1-00001.step` / `bzx84c15-r1-00001.glb` are the bare package body.
