ESDA0504T5 from Leiditech, in a SOT-553. 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 | passive | Protected line 1 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 2 | GND | power_in | Common ground node of the TVS array, tied to the centre node joining the diode pairs in the pin configuration drawing. |
| 3 | IO3 | passive | Protected line 3 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 4 | IO4 | passive | Protected line 4 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
| 5 | IO5 | passive | Protected line 5 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2. |
