**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-363

SMF05CT1G-P from TECH PUBLIC, in a SOT-363. 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 | Protected I/O line (Note 1 lists pins 1, 3, 4, 5 and 6 as I/O); steered TVS channel with 5V max reverse working voltage and ±30kV IEC 61000-4-2 ESD rating. |
| 2 | GND | power_in | Common pin of the 5-line TVS array, not listed as an I/O pin in Note 1; the pin diagram shows it tied to the common node of the diode network. |
| 3 | I/O2 | passive | Protected I/O line (Note 1 lists pins 1, 3, 4, 5 and 6 as I/O); steered TVS channel with 5V max reverse working voltage and ±30kV IEC 61000-4-2 ESD rating. |
| 4 | I/O3 | passive | Protected I/O line (Note 1 lists pins 1, 3, 4, 5 and 6 as I/O); steered TVS channel with 5V max reverse working voltage and ±30kV IEC 61000-4-2 ESD rating. |
| 5 | I/O4 | passive | Protected I/O line (Note 1 lists pins 1, 3, 4, 5 and 6 as I/O); steered TVS channel with 5V max reverse working voltage and ±30kV IEC 61000-4-2 ESD rating. |
| 6 | I/O5 | passive | Protected I/O line (Note 1 lists pins 1, 3, 4, 5 and 6 as I/O); steered TVS channel with 5V max reverse working voltage and ±30kV IEC 61000-4-2 ESD rating. |
