SMBJ28CA

Shandong Jingdao Microelectronics · ESD And Surge Protection (TVS/ESD) · SMB

SMBJ28CA from Shandong Jingdao Microelectronics, in a SMB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Cathode passive Cathode terminal listed in the PINNING table for the SMB package; the datasheet gives no separate electrical limits for this pin, and polarity is shown only for the unipolar symbol.
2 Anode passive Anode terminal listed in the PINNING table for the SMB package; the datasheet gives no separate electrical limits for this pin, and polarity is shown only for the unipolar symbol.

  • Symbol: SMBJ28CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smbj28ca-etched.step / smbj28ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj28ca.step / smbj28ca.glb are the bare package body.

Provenance

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

  • Datasheet: Shandong Jingdao Microelectronics datasheet (4 pp, sha256 11a0cb29fa635344, retrieved 2026-10-12, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-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: KiCad official libraries (CC-BY-SA 4.0).
