ESDBL7V0D3 from Changjing, in a SOD-323. 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 | A1 | passive | One terminal of the bi-directional ESD protection diode (reverse stand-off voltage 7 V, breakdown 8.2 V at 1 mA), connected to the protected line or to ground since polarity is interchangeable. |
| 2 | A2 | passive | Second terminal of the bi-directional ESD protection diode (reverse stand-off voltage 7 V, clamping 17 V at IPP=5 A), connected to the protected line or to ground since polarity is interchangeable. |
