SESM12

SEMIWARE · ESD Protection Devices · SOT-23

SESM12 from SEMIWARE, in a SOT-23. 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 1 passive TVS diode line 1 (anode of first diode); protects one line against ESD, with the SESM12 at VRWM 12.0 V max, VBR 13.3 V min at 1 mA.
2 2 passive TVS diode line 2 (anode of second diode); protects a second unidirectional line, with the SESM12 at VRWM 12.0 V max, VBR 13.3 V min at 1 mA.
3 3 passive Common cathode of both TVS diodes; for one bidirectional line, use pins 1 and 3 or 2 and 3 as shown in the pin diagram.

  • Symbol: SESM12
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sesm12-etched.step / sesm12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sesm12.step / sesm12.glb are the bare package body.

Provenance

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

  • Datasheet: SEMIWARE datasheet (4 pp, sha256 f3fecd7d1c03f780, retrieved 2026-10-22, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-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).
