SR340L from NH, in a DO-27. 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 white band on the package body; the axial lead on the banded end. |
| 2 | A | passive | Anode, the axial lead opposite the white cathode band; device is rated 3 A average forward current and 40 V maximum repetitive peak reverse voltage. |
