BZX84C13A from Shandong Jingdao Microelectronics, 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 (Suffix A), shown in the page 1 drawing on the opposite side from pin 3; the zener voltage is 12.4V min to 14.1V max at 5mA for the BZX84C13A. |
| 2 | NC | unconnected | No internal connection in the single-diode Suffix A configuration shown in the page 1 drawing. |
| 3 | K | passive | Cathode of the single zener diode (Suffix A), shown in the page 1 drawing at the top of the package; power dissipation is limited to 350mW maximum. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
BZX84C13A - 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, 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)
