US1D_R1_00101 from PANJIT International, 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 | Cathode | passive | Cathode terminal, marked by the color band; for the US1D it blocks up to 200 V VRRM and 200 V DC, and carries 1 A maximum average forward current. |
| 2 | Anode | passive | Anode terminal; forward current up to 1 A average (30 A peak 8.3 ms surge) flows in here, with VF of 1 V max at 1 A for the US1D. |
