1N4148WSX from Shenzhen JingYang, in a SOD-323. 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 of the diode; the datasheet shows pin 1 as CATHODE, with a 75 V working peak reverse voltage (VRRM/VRWM/VR) and 100 V non-repetitive peak reverse voltage (VRM). |
| 2 | A | passive | Anode of the diode; the datasheet shows pin 2 as ANODE, with 150 mA average rectified output current (Io) and a forward voltage of 1.25 V max at IF=150 mA. |
