ESDAULC5-1BF4 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 | Pin1 | passive | One terminal of the bidirectional single-line TVS diode; marked with a bar/line marking on the package for orientation, per IEC 61000-4-2 dynamic resistance measured I/O to GND (0.3 Ω typ, 100 ns pulse). |
| 2 | Pin2 | passive | Second terminal of the bidirectional single-line TVS diode, used with Pin1 to clamp ESD transients (VCL = 13.5 V typ at 8 kV contact discharge, Rd = 0.3 Ω typ). |
