US1J from Guangdong Hottech, in a DO-214AC(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 cathode band; US1J is rated 600 V VRRM, 1.0 A average forward current at TA=75 °C. |
| 2 | A | passive | Anode terminal, opposite the cathode band; US1J has 1.7 V maximum forward voltage at 1 A and 30.0 A peak surge current. |
