SMF6.5A from DOWO, 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, the end marked by the colour band on the unidirectional SMF6.5A; it goes to the protected line and is the positive side for reverse standoff (VRWM 6.5 V, VBR 7.22 to 7.98 V at 10 mA). |
| 2 | A | passive | Anode, the end without the colour band on the unidirectional SMF6.5A; it is normally tied to ground and conducts forward with VF of 3.5 V max at 25 A. |
