PTZ6.8B-MS from MSKSEMI, in a SMA. 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, the end marked by the color band; Zener voltage VZ of 6.8 V typ. (7.280 V and 7.70 V listed in the MIN./TYP./MAX. columns) at IZT = 40 mA. |
| 2 | A | passive | Anode terminal of the Zener diode, opposite the color-banded cathode end; 1.0 W maximum power dissipation at 25 °C. |
