ESDLC3V3D3B-ES from ElecSuper, 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 | IO1 | bidirectional | Connects to the IO line and, as a bi-directional TVS, protects it to ±25kV contact and air discharge per IEC61000-4-2 with 200W peak pulse power (8/20us). |
| 2 | IO2 | bidirectional | Connects to the IO line per the pin configuration table, with no pin-specific limits stated beyond the device-level ratings. |
