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). |
