AQHV12-01LTG-C

Littelfuse · ESD Protection Devices · SOD-523

AQHV12-01LTG-C from Littelfuse, in a SOD-523. 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/O 1 bidirectional One of the two bidirectional I/O terminals of the AQHV12-C TVS, which clamps I/O-to-I/O with a 12 V reverse standoff voltage (VRWM) and up to 10 A peak pulse current (8/20 µs).
2 2 bidirectional The second bidirectional I/O terminal of the AQHV12-C TVS, which clamps I/O-to-I/O with a 12 V reverse standoff voltage (VRWM) and up to 10 A peak pulse current (8/20 µs).
