ESDAXLC18-1BF4 from STMicroelectronics, 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 | Pin1 | passive | Bidirectional TVS line terminal, marked with the pin 1 bar; leakage specified pin 1 to pin 2 at VRM = 18 V (<1 typ, 30 nA max), line capacitance 0.3/0.45/0.6 pF at 0 V, 1 MHz. |
| 2 | Pin2 | passive | Second bidirectional TVS terminal, interchangeable with pin 1, protecting the RF/NFC line to ±10 kV contact and ±30 kV air IEC 61000-4-2 discharge. |
