ESD9L3.3ST5GB from FUXINSEMI, in a DFN1006-2. 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 | 1 | passive | One terminal of the bidirectional TVS diode, which protects one bi-directional I/O line with a 3.3 V reverse working voltage, 4.0 A peak pulse current (8/20 µs) and ±20 kV IEC 61000-4-2 air/contact ESD rating. |
| 2 | 2 | passive | The other terminal of the bidirectional TVS diode, which protects one bi-directional I/O line with a 3.3 V reverse working voltage, 4.0 A peak pulse current (8/20 µs) and ±20 kV IEC 61000-4-2 air/contact ESD rating. |
