1N4148WT T4 from Changjing, in a SOD-523. 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 terminal, the end marked by the bar on the package body; the diode allows reverse voltage up to VR = 75 V (VRM 100 V non-repetitive peak). |
| 2 | A | passive | Anode terminal (+), the end opposite the cathode bar; the diode carries up to 150 mA average rectified current (IO) and 300 mA forward continuous current (IFM). |
