PTZ9.1B-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; the zener voltage VZ is 9.1 V typical (9.747 V measured, 10.2 V max) at IZT = 40 mA. |
| 2 | A | passive | Anode; power dissipation is limited to 1.0 W at 25 °C with junction temperature up to 150 °C. |
