ZMM4V3PF-M from ST Semtech, in a LL-34. 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 of the glass body carrying the cathode mark band; it goes positive in Zener (reverse) operation, with a nominal Zener voltage of 4.3 V (4…4.6 V) at IZT = 5 mA for ZMM4V3PF. |
| 2 | A | passive | Anode, the end opposite the cathode mark band; forward voltage is 1 V max at IF = 100 mA. |
