Changjing · Switching Diodes · SOD-123
1N4448W from Changjing, 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 striped end of the SOD-123 body marked with the minus sign; the datasheet gives a 75 V working peak reverse voltage and 100 V non-repetitive peak reverse voltage. |
| 2 | A | passive | Anode, the end marked with the plus sign; the datasheet gives 250 mA average rectified output current and 500 mA forward continuous current. |
