1N5352BG 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 | Cathode | passive | Cathode end of the zener diode, indicated by the polarity band; the 15 V (14.25-15.75 V at 75 mA) zener operates with this lead positive relative to the anode in reverse breakdown. |
| 2 | Anode | passive | Anode end of the zener diode (lead opposite the polarity band); forward voltage is 1.2 V max at IF = 1.0 A. |
