2EZ7.5D5 from EIC Semicon, 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, marked by the color band on the DO-41 axial package; the zener (VZ 7.5 V at IZT 66.5 mA) is reverse-biased with this lead positive. |
| 2 | A | passive | Anode, the axial lead at the end opposite the color band of the DO-41 package; maximum forward voltage is 1.2 V at IF = 200 mA. |
