ESD12VL1BA-MS

MSKSEMI · ESD Protection Devices · SOD-323

ESD12VL1BA-MS from MSKSEMI, in a SOD-323. 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 K passive Cathode: the banded/marked end per the datasheet; pad 1 of the KiCad diode footprint.
2 A passive Anode.

CAD (KiCad official)

  • Symbol: ESD12VL1BA-MS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esd12vl1ba-ms-etched.step / esd12vl1ba-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd12vl1ba-ms.step / esd12vl1ba-ms.glb are the bare package body.

Provenance

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

  • Datasheet: MSKSEMI datasheet (7 pp, sha256 2b6256d8da2fdb40, retrieved 2026-11-04, tier: lcsc)
  • 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).
