AQ1250-01ETG

Littelfuse · TVS · SOD-882

AQ1250-01ETG from Littelfuse, in a SOD-882. 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 unidirectional TVS diode (VRWM 5 V, VBR 5.2 to 5.5 V at 1 mA, 50 A 8/20 µs surge), with the pin 1 ID optional on the package bottom.
2 2 passive Terminal 2 of the unidirectional TVS diode (VRWM 5 V, VBR 5.2 to 5.5 V at 1 mA, 50 A 8/20 µs surge), marked as Pin 2 in the tape orientation drawing.
