SF56G弯脚N型
YFW · Diodes - Fast Recovery Rectifiers · DO-27
SF56G弯脚N型 from YFW, in a DO-27. 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, identified by the cathode mark band on the DO-201AD/DO-27 body; SF56G is rated 400 V VRRM, 5.0 A average forward current. |
| 2 | A | passive | Anode terminal at the end opposite the cathode mark of the DO-201AD/DO-27 axial package; SF56G blocks 400 V DC (VDC) and has 1.25 V max forward voltage at 5.0 A. |
