SF28G
LGE · Fast Recovery/High Efficiency Diode · DO-15
SF28G from LGE, 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, marked by the color band on the molded plastic DO-15 case; blocks up to 600 V DC (VRRM 600 V, VRMS 420 V) for the SF28G. |
| 2 | A | passive | Anode terminal at the end opposite the color band; carries 2.0 A average forward current at TA=55 °C with 0.375 in (9.5 mm) lead length and a maximum VF of 1.7 V at 2.0 A for the SF28G. |
