PTZ16B-MS from MSKSEMI, in a SMA(DO-214AC). 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, identified by the color band on the SMA molded body; the Zener voltage VZ is 16.2 V min, 16.86 V typ and 18.3 V max at 20 mA for the PTZ16B-MS. |
| 2 | A | passive | Anode, the end opposite the color band; maximum power dissipation is 1.0 W at 25 °C ambient. |
