2EZ120D5 from SUNMATE Elec, in a DO-41. 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; zener diode with 120 V nominal Vz at 4.2 mA IZT (±5%), 2.0 W dissipation at TL = 75 °C. |
| 2 | A | passive | Anode, the end opposite the color band; maximum forward voltage 1.2 V at IF = 200 mA. |
