AQ24COM-02HTG from Littelfuse, in a SOT-23-3. 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 | TVS-protected I/O channel 1, protected to GND with 24 V reverse standoff, 26 V min breakdown at 1 mA and ±30 kV IEC 61000-4-2 ESD withstand. |
| 2 | I/O2 | passive | TVS-protected I/O channel 2, protected to GND with 24 V reverse standoff, 26 V min breakdown at 1 mA and ±30 kV IEC 61000-4-2 ESD withstand. |
| 3 | GND | power_in | Common ground/reference pin to which both I/O channels are clamped, as shown in the functional block diagram and the I/O to GND test conditions. |
