Vishay Intertech · Schottky Barrier Diodes (SBD) · DO-41
1N5819-E3 from Vishay Intertech, 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 | K | passive | Cathode, marked by the color band on the case; for the 1N5819 maximum repetitive peak reverse voltage is 40 V and average forward current is 1.0 A. |
| 2 | A | passive | Anode lead at the end opposite the color band; forward voltage is 0.600 V max at 1.0 A for the 1N5819. |
