SMS12CT1G

onsemi · ESD Protection Devices · TSOP-6

SMS12CT1G from onsemi, in a TSOP-6. 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 CATHODE passive Cathode of one protected line in the common-anode array; it clamps transients and ESD on that line relative to the common anode.
2 ANODE passive Common anode shared by all five protection diodes, which is tied to the GND reference in the application circuits.
3 CATHODE passive Cathode of one protected line in the common-anode array; it clamps transients and ESD on that line relative to the common anode.
4 CATHODE passive Cathode of one protected line in the common-anode array; it clamps transients and ESD on that line relative to the common anode.
5 CATHODE passive Cathode of one protected line in the common-anode array; it clamps transients and ESD on that line relative to the common anode.
6 CATHODE passive Cathode of one protected line in the common-anode array; it clamps transients and ESD on that line relative to the common anode.
