GF1G

onsemi · Diodes - General Purpose · SMA(DO-214AC)

GF1G from onsemi, 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 K passive Cathode terminal, marked by the color band on the SMA package; GF1G is rated for 400 V VRRM and 1.0 A average forward current.
2 A passive Anode terminal at the end opposite the color band; forward voltage is 1.2 V maximum at 1.0 A for the GF1G.
