SMAZ9V1-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, marked by the color band on the SMA molded plastic case; Zener voltage VZ 9.1 V nominal (8.65 to 9.56 V) at IZT = 50 mA. |
| 2 | A | passive | Anode; the opposite end from the color band, with maximum power dissipation of 1.0 W at Ta = 50 °C. |
