BAS21SLT1G

onsemi · Switching Diodes · SOT-23

BAS21SLT1G from onsemi, 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 ANODE passive Anode of the first diode in the dual series pair; the device is rated for 250 Vdc continuous reverse voltage and 225 mAdc peak forward current.
2 CATHODE passive Cathode of the second diode in the dual series pair; the device is rated for 250 Vdc continuous reverse voltage and 225 mAdc peak forward current.
3 CATHODE/ANODE passive Common internal node joining the cathode of the first diode and the anode of the second diode in the series configuration.

  • Symbol: BAS21SLT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bas21slt1g-etched.step / bas21slt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas21slt1g.step / bas21slt1g.glb are the bare package body.

Provenance

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

  • Datasheet: onsemi datasheet (3 pp, sha256 d1b247c0d5224e0b, retrieved 2026-10-09, 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.
