UF204
SUNMATE Elec · Fast Recovery / High Efficiency Diodes · DO-15
UF204 from SUNMATE Elec, in a DO-15. 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, identified by the cathode band on the DO-15 body; the diode blocks up to 400V (UF204 VRRM) and the datasheet gives only the band polarity marking. |
| 2 | A | passive | Anode terminal of the DO-15 axial diode, conducting 2.0A average rectified output current at TA=55°C when forward biased. |
