FUXINSEMI · Diodes - General Purpose · DO-214AC(SMA)
M7A from FUXINSEMI, 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 | Cathode | passive | Cathode terminal of the rectifier; the color band on the body denotes the cathode end, so this is the polarity reference. |
| 2 | Anode | passive | Anode terminal of the rectifier diode, opposite the cathode (pin 1). |
