1N4148G-CA2-R from UTC Unisonic Tech, 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 | A | passive | Anode terminal of the 1N4148 high-speed switching diode, with a maximum repetitive reverse voltage (VRRM) of 100 V and average rectified forward current (IF(AV)) of 200 mA. |
| 2 | C | passive | Cathode terminal of the 1N4148 high-speed switching diode, which conducts forward current from the anode when forward-biased. |
