ZMM5V1 from YONGYUTAI, 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 with the cathode band; connected to the positive side in Zener operation, with VZ 4.8...5.4 V (nominal 5.1 V) at IZT = 5 mA. |
| 2 | A | passive | Anode, the end without the cathode band; Ptot is 500 mW and Tj is 175 °C max, valid provided that the electrodes are kept at ambient temperature. |
