1N4001RLG from onsemi, in a DO-41. 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, marked by the polarity band on the body; the 1N4001 is rated for a peak repetitive reverse voltage (VRRM) of 50 V and an average rectified forward current (IO) of 1.0 A at TA = 75°C. |
| 2 | ANODE | passive | Anode, opposite the polarity band; the device operates over a junction and storage temperature range of −65 to +175 °C. |
