BZX84C75LT1G 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 terminal of the Zener diode; the cathode is identified by the polarity band on the package, so pin 1 is the anode. |
| 2 | NO CONNECTION | unconnected | No connection; this pin is not connected internally and is listed as NO CONNECTION in the datasheet pinout. |
| 3 | CATHODE | passive | Cathode terminal of the Zener diode, marked by the polarity band; the BZX84C75LT1G has a nominal Zener voltage VZ of 75 V at IZT = 5 mA. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
BZX84C75LT1G - 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)
