RR601BM4STL from ROHM Semicon, in a TO-252. 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 | NC | unconnected | Open pin with no internal connection, as shown in the Structure diagram. |
| 2 | K | passive | Cathode, connected to the mounting tab (marked (2) in the outline); the part is rated 400 V VRM/VR, 6 A average rectified current at Tc=98°C. |
| 3 | A | passive | Anode terminal of the rectifier diode, with forward voltage 1.1 V max at IF=6A. |
