CFRM104-HF from Comchip, in a SOD-123. 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 | K | passive | Cathode, marked by the cathode band on the Mini SMA/SOD-123 body; the part is rated for 400V VRRM/VR and 1.0A forward rectified current. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the part has 1.3V maximum forward voltage at IF=1.0A and 30A peak forward surge current. |
