BAS21-QR

Nexperia · Switching Diodes · SOT-23

BAS21-QR from Nexperia, 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 A passive Anode of the diode; the datasheet gives no pin-specific limit, and the device ratings apply (VRRM 250 V, continuous forward current 200 mA).
2 n.c. unconnected Not connected; the pinning table assigns it no electrical function.
3 K passive Cathode of the diode; reverse voltage is limited to VR 200 V (VRRM 250 V).

CAD (KiCad official)

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

Provenance

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

  • Datasheet: Nexperia datasheet (10 pp, sha256 eb26eb3f9f8e1993, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
