US1D-E3 from Vishay Intertech, in a SMA(DO-214AC). 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 end marked by the color band on the SMA (DO-214AC) package; the diode blocks up to 200 V (VRRM/VDC for US1D). |
| 2 | A | passive | Anode, the end opposite the cathode color band; US1D conducts 1.0 A average forward current (IF(AV)) at TL = 110 °C. |
