PTZTE2533B-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 with the color band; the 33 V zener (VZ 33.0 V min to 37.0 V max at 10 mA, marking 33B) is reverse biased with this pin positive. |
| 2 | A | passive | Anode, the end opposite the color band; connects to the more negative side of the circuit in normal zener regulation (1.0 W maximum power dissipation). |
