DF3A6.8FUT1G from onsemi, in a SC-70. 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 | CATHODE | passive | Cathode of one unidirectional zener junction, used with pin 3 as the common anode to clamp a line to a breakdown voltage of 6.4 to 7.2 V at 5.0 mA. |
| 2 | CATHODE | passive | Cathode of the second unidirectional zener junction, used with pin 3 as the common anode to protect a separate line with the same 6.4 to 7.2 V breakdown at 5.0 mA. |
| 3 | ANODE | passive | Common anode shared by both zener junctions, so one package protects two separate lines (circuit tied to pins 1 and 3 or 2 and 3). |
