US1GG

Shikues · Fast Recovery / High Efficiency Diodes · SMA

US1GG from Shikues, 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 of the US1GG rectifier, rated for a maximum repetitive peak reverse voltage (VRRM) of 400 V and an average forward rectified current of 1.0 A at Tc = 125 °C.
2 Anode passive Anode terminal of the US1GG rectifier, forming the forward-current path with the cathode, with a maximum instantaneous forward voltage of 1.3 V at 1 A.
