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

TPCM1293A-02SO 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 | NC | unconnected | No connect pin with no internal connection shown in the device schematic. |
| 2 | VN | power_in | Negative (ground) reference node of the TVS array, to which the I/O pins are clamped, as shown in the device schematic. |
| 3 | CH1 | passive | Protected line channel 1 (I/O) with 0.3 pF typical I/O-to-I/O capacitance, 5.5 V max reverse working voltage and ±25 kV air / ±20 kV contact ESD rating. |
| 4 | CH2 | passive | Protected line channel 2 (I/O) with 0.3 pF typical I/O-to-I/O capacitance, 5.5 V max reverse working voltage and ±25 kV air / ±20 kV contact ESD rating. |
| 5 | NC | unconnected | No connect pin with no internal connection shown in the device schematic. |
| 6 | VP | power_in | Positive rail node of the TVS array, connected to the steering diodes in the device schematic. |
