STZ6.8NT146 from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 | K1 | passive | Cathode of the first Zener element (VZ 6.47 to 7.14 V at IZ=5 mA); total power for both elements is 200 mW. |
| 2 | K2 | passive | Cathode of the second Zener element (VZ 6.47 to 7.14 V at IZ=5 mA); total power for both elements is 200 mW. |
| 3 | A | passive | Common anode of the twin Zener diodes, the single lead on the opposite side of the package from pins 1 and 2. |
