Suzhou Good-Ark Elec · Diodes - Fast Recovery Rectifiers · DO-41
FR103 from Suzhou Good-Ark Elec, in a DO-41. 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 end of the axial-lead rectifier, marked by the color band on the DO-41 body. |
| 2 | A | passive | Anode lead of the axial-lead rectifier (end opposite the color band); the datasheet states 1.0 A average forward current at TA=55°C. |
