SZ6515 from EIC Semicon, in a SMB(DO-214AA). 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 SMB molded body; zener is reverse-biased with this end positive (VZ 15 V nominal at IZT 75 mA for SZ6515). |
| 2 | A | passive | Anode end of the zener diode, with maximum forward voltage of 1.2 V at IF = 1.0 A. |
