ESD5471X from TECH PUBLIC, 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	Terminal 1 of the 1-line bidirectional TVS diode, shown as pin 1 in the Terminal Connections diagram and marking figure; the datasheet gives no separate function text for this terminal, and the device is rated at a 5 V maximum reverse working voltage (VRWM) with 7 A peak pulse current (8/20 µs).
2	2	passive	Terminal 2 of the 1-line bidirectional TVS diode, shown as pin 2 in the Terminal Connections diagram and marking figure; the datasheet gives no separate function text for this terminal, and the device is rated at a 5 V maximum reverse working voltage (VRWM) with 7 A peak pulse current (8/20 µs).
