CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
BZX84C3V3S-7-F - Footprint:
Package_TO_SOT_SMD:SOT-363_SC-70-6 - 3D model: SOT-363, generated on the KiCad land (body 1.25 x 2.1 mm, terminals on the pads, 0.95 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)
