SMF5924A from Changjing, in a SOD-123FL. 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 bar on the package; for the SMF5924A the nominal Zener voltage is 9.1V (8.65V to 9.56V) at IZT=41.2mA. |
| 2 | A | passive | Anode of the Zener diode; maximum power dissipation is 1.5W at TL=75°C and the forward voltage is max 1.5V at IF=200mA. |
