SC3530-01LTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOD-523

SC3530-01LTG 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 1 passive Pin 1 is one of the two terminals of this unidirectional TVS diode array, labelled 1 in the functional block diagram and the SOD523 pad layout; the datasheet does not state whether it is the I/O or the GND terminal.
2 2 passive Pin 2 is the other of the two terminals of this unidirectional TVS diode array, labelled 2 in the functional block diagram and the SOD523 pad layout; the datasheet does not state whether it is the I/O or the GND terminal.
