D1213A-01W-7

Diodes Incorporated · ESD Protection Devices · SOT-323

D1213A-01W-7 from Diodes Incorporated, in a SOT-323. 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 CH1 passive ESD-protected channel input (1 channel, 0.85pF typical capacitance) clamped by diodes to VP and VN, with DC voltage limited to (VN - 0.5) to (VP + 0.5) V.
2 VP power_in Positive supply/reference rail of the TVS array, operating supply 3.3 to 5.5 V (VP - VN maximum rating 6.0 V).
3 VN power_in Negative reference rail (ground) of the TVS array, return for VP and the channel clamp diodes.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin • Terminals: Matte Tin Finish annealed over Alloy 42 leadframe (Lead Free Plating). Solderable per MIL-STD-202, Method 208 1

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

  • Symbol: D1213A-01W-7
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323, generated on the KiCad land (body 1.3 x 2.1 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)
  • 3D model files: d1213a-01w-7-etched.step / d1213a-01w-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); d1213a-01w-7.step / d1213a-01w-7.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 4de5ac260493417b, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
