1N5355BG from onsemi, in a DO-201. 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, indicated by the polarity band; the zener (reverse) voltage for the 1N5355B is 18 V nominal (17.1 V min to 18.9 V max) at IZT = 65 mA. |
| 2 | A | passive | Anode; the forward voltage is 1.2 V max at IF = 1.0 A. |
