onsemi · Fast Recovery / High Efficiency Diodes · SOD-123 FL
RS1MFA from onsemi, in a SOD-123 FL. 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, identified by the color band on the package; the RS1MFA is rated for a repetitive peak reverse voltage (VRRM) of 1000 V. |
| 2 | Anode | passive | Anode terminal; the device is rated for an average forward rectified current (IF(AV)) of 0.8 A. |
