1N5819RLG 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, identified by the polarity band on the body; the 1N5819 is rated for 40 V VRRM and 1.0 A average rectified forward current (IO). |
| 2 | ANODE | passive | Anode, the lead opposite the polarity band; Style 1 of Case 59-10 defines pin 1 as cathode and pin 2 as anode. |
