PTZ7.5B-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, the end marked by the color band; the Zener diode is reverse-biased with this pin positive, with VZ of 7.5 V typical at IZT = 40 mA for PTZ7.5B-MS. |
| 2 | A | passive | Anode, the end opposite the color band; connects to the lower potential side in normal Zener regulation use. |
