ESDA19SC6 from STMicroelectronics, in a SOT-23-6L. 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 | I/O1 | passive | Protected data line 1 (unidirectional ESD channel), clamping positive transients just above the 19 V min breakdown level and negative transients to a diode drop below ground. |
| 2 | GND | power_in | Common ground/return of the array, connected internally to pin 5 and shared by all four protection channels. |
| 3 | I/O2 | passive | Protected data line 2 (unidirectional ESD channel), clamping positive transients just above the 19 V min breakdown level and negative transients to a diode drop below ground. |
| 4 | I/O3 | passive | Protected data line 3 (unidirectional ESD channel), paired with pin 3 on the same side of the common node, with the same clamping behavior. |
| 5 | GND | power_in | Common ground/return of the array, connected internally to pin 2 and shared by all four protection channels. |
| 6 | I/O4 | passive | Protected data line 4 (unidirectional ESD channel), paired with pin 1 on the same side of the common node, with the same clamping behavior. |
