BAW56LT3G

onsemi · Diodes - General Purpose · SOT-23

BAW56LT3G from onsemi, in a SOT-23. 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 CATHODE passive Cathode of the first switching diode (Style 12 pin 1); each diode is rated VR 70 V, IF 200 mA.
2 CATHODE passive Cathode of the second switching diode (Style 12 pin 2); each diode is rated VR 70 V, IF 200 mA.
3 ANODE passive Common anode of both diodes (Style 12 pin 3); each diode is rated IF 200 mA, with 2.0 A forward surge current (60 Hz, 1 cycle).

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

  • Symbol: BAW56LT3G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 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: baw56lt3g-etched.step / baw56lt3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); baw56lt3g.step / baw56lt3g.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (4 pp, sha256 14669b3e97e9e1b9, 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).
