1N5388B from LGE, in a DO-15. 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 cathode band; positive terminal in zener (reverse breakdown) operation, with VZ 200 V at IZT 5.0 mA for the 1N5388B and 5.0 W maximum DC power dissipation at TL=75. |
| 2 | A | passive | Anode terminal, opposite the cathode band end; lead terminal of the axial DO-15 package with maximum junction temperature TJ of 150. |
