BZX55C16V from ST Semtech, in a DO-35. 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 lead, marked by the cathode band on the glass DO-35 case; positive-side lead in Zener (reverse) operation, with Zener voltage 15.3...17.1 V at IZT = 5 mA for the 16 V grade. |
| 2 | A | passive | Anode lead at the end opposite the cathode band; Ptot is 500 mW only if leads are kept at ambient temperature 8 mm from the case, and forward voltage is max 1 V at IF = 100 mA. |
