AQ24COM-02HTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOT-23-3

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.
