ESD7481MUT5G from onsemi, in a 0201. 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 terminal of the bidirectional ESD protection diode; breakdown voltage (6.0 V min at IT = 1 mA) is tested from pin 1 to pin 2 and from pin 2 to pin 1, with a working reverse voltage of 3.3 V. |
| 2 | Anode | passive | Anode terminal of the bidirectional ESD protection diode; breakdown voltage is tested from pin 2 to pin 1 as well as from pin 1 to pin 2, with a working reverse voltage of 3.3 V. |
