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: Lead Free Plating (Matte Tin Finish). Solderable per MIL-STD-202, Method 208 1

CAD (KiCad official)

  • Symbol: B550CQ-13-F
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: b550cq-13-f-etched.step / b550cq-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b550cq-13-f.step / b550cq-13-f.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (6 pp, sha256 48273026e7a2127a, retrieved 2026-11-02, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
