BAS21

Nexperia · Diodes - General Purpose · SOT-23

BAS21 from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Anode of the switching diode. Forward current flows from anode (pin 1) to cathode (pin 3); VF ≤ 1 V at IF = 100 mA.
2 NC unconnected Not connected. No internal bond; leave floating or tie to any convenient net.
3 K passive Cathode of the switching diode. Reverse voltage rating VR = 200 V (VRRM = 250 V); reverse current ≤ 100 nA at VR = 200 V, Tj = 25 °C.

  • Symbol: BAS21
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bas21-etched.step / bas21-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas21.step / bas21.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (10 pp, sha256 4632cdc90d8753d1, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
