2EZ12
amsem · Zener Diodes · DO-15
2EZ12 from amsem, in a DO-15. 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 with the color band, which denotes the positive end; primary conduction path for heat is through the cathode lead. |
| 2 | A | passive | Anode, the end opposite the color band; axial lead of the DO-204AC (DO-15) package. |
