S1DFL from onsemi, in a SOD-123F. 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 | Cathode | passive | Cathode terminal, identified by the band on the package; for the S1DFL the VRRM is 200 V and the average forward current IF(AV) is 1 A. |
| 2 | Anode | passive | Anode terminal of the rectifier, opposite the banded cathode; the datasheet gives no separate pin limit for this terminal beyond the device ratings. |
