ESDL031-1BF4 from STMicroelectronics, in a 0201. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | Terminal of the bidirectional single-line TVS diode; marked with black pin-1 identifier on the package top marking, connect to the line to be protected against ESD/EOS transients (VRM = 3.3 V, clamps to VCL as low as 6.3 V at 16 A TLP). |
| 2 | I/O2 | passive | Terminal of the bidirectional single-line TVS diode; opposite terminal from pin 1, connect to the line to be protected against ESD/EOS transients (VRM = 3.3 V, clamps to VCL as low as 6.3 V at 16 A TLP). |
