AQ24COM-02JTG from Littelfuse, in a SC-70-3. 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	I/O1	passive	Bidirectional TVS I/O channel 1. Connect to the protected signal line; internally clamped to pin 3 (GND) via a bidirectional TVS leg with 24 V VRWM, 26-33 V VBR at 1 mA, and typical clamp voltage of 38.5 V at 1 A / 50.0 V at 5 A (8/20 μs). Typical 13 pF capacitance to GND at 0 V bias, 1 MHz.
2	I/O2	passive	Bidirectional TVS I/O channel 2. Connect to the protected signal line; internally clamped to pin 3 (GND) via a bidirectional TVS leg with 24 V VRWM, 26-33 V VBR at 1 mA, and typical clamp voltage of 38.5 V at 1 A / 50.0 V at 5 A (8/20 μs). Typical 13 pF capacitance to GND at 0 V bias, 1 MHz.
3	GND	passive	Common ground / reference return pin shared by both TVS channels. Serves as the common node for clamping I/O1 and I/O2 during ESD or surge events; tie to the system ground plane with a low-impedance path for effective clamping.
