US1GA
FUXINSEMI · High Effic Rectifier · SMA(DO-214AC)
US1GA from FUXINSEMI, 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 | Cathode | passive | Cathode terminal, marked by the color band on the package; the datasheet rates US1GA at a maximum repetitive peak reverse voltage (VRRM) of 400 V and a maximum average forward rectified current of 1.0 A at TL=100°C. |
| 2 | Anode | passive | Anode terminal, opposite the cathode band; the datasheet specifies a maximum instantaneous forward voltage of 1.4 V at 1.0 A and a peak forward surge current of 30.0 A (8.3 ms half sine-wave). |
