1N5352B 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) operation, with VZ 15 V at IZT 75 mA for the 1N5352B. |
| 2 | A | passive | Anode terminal of the axial zener diode, opposite the cathode band; DC power dissipation is 5.0 W at TL=75°C. |
