TPCM1293A-04SO

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-6

TPCM1293A-04SO from TECH PUBLIC, in a SOT-23-6. 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 CH1 bidirectional I/O line protected by the TVS array, rated for 5.5 V reverse working voltage to ground with 6 V minimum breakdown at 1 mA and 0.35 pF typical I/O-to-I/O capacitance.
2 VN power_in Schematic-labelled non-I/O pin (VN) of the TVS array; the datasheet gives no separate electrical limit for it beyond the note that I/O pins are 1, 3, 4 and 6.
3 CH2 bidirectional I/O line protected by the TVS array, rated for 5.5 V reverse working voltage to ground with 6 V minimum breakdown at 1 mA and 0.35 pF typical I/O-to-I/O capacitance.
4 CH3 bidirectional I/O line protected by the TVS array, rated for 5.5 V reverse working voltage to ground with 6 V minimum breakdown at 1 mA and 0.35 pF typical I/O-to-I/O capacitance.
5 VP power_in Schematic-labelled power line (VP) of the TVS array; the datasheet gives no separate electrical limit for it beyond the statement that one power line is protected.
6 CH4 bidirectional I/O line protected by the TVS array, rated for 5.5 V reverse working voltage to ground with 6 V minimum breakdown at 1 mA and 0.35 pF typical I/O-to-I/O capacitance.
