3EZ5.6AD5 from YFW, 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 by the color band; the Zener is reverse-biased with this pin positive, with nominal VZ 5.6 V (5.32 to 5.88 V) at IZT 134 mA for the 3EZ5.6AD5. |
| 2 | A | passive | Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA. |
