3EZ24D5 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; positive with respect to the anode in zener operation (24 V nominal VZ at 31 mA IZT for 3EZ24D5, ±5% tolerance). |
| 2 | A | passive | Anode, the axial lead opposite the color band end of the DO-41 package. |
