US1MD from ST Semtech, in a SMA. 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, marked by the color band on the SMA (DO-214AC) body; the US1MD blocks up to 1000 V DC (VRRM 1000 V) and conducts 1 A average forward current. |
| 2 | A | passive | Anode terminal at the end opposite the color band; the maximum forward voltage is 1.7 V at 1 A and the peak forward surge current is 30 A (8.3 ms half sine-wave). |
