DF3A5.6LFV from TOSHIBA, in a SOT-723. 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 | CATHODE1 | passive | Cathode terminal of the first of the two Zener elements in the package, used for ESD protection only (datasheet: not intended for constant-voltage diode use). |
| 2 | CATHODE2 | passive | Cathode terminal of the second of the two Zener elements in the package, used for ESD protection only (datasheet: not intended for constant-voltage diode use). |
| 3 | ANODE | passive | Single anode terminal shared by the two Zener elements; the datasheet gives no pin-specific electrical limits beyond the device ratings (Pd 150 mW, Tj 150 °C, Tstg −55 to 150 °C). |
