CM1293A-02SR from TECH PUBLIC, in a SOT-143. 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 | passive | Channel 1 I/O protected line, rated 1.0pF max to GND with 5.5V max reverse standoff voltage and ±15kV IEC 61000-4-2 ESD protection. |
| 2 | CH2 | passive | Channel 2 I/O protected line, rated 1.0pF max to GND with 5.5V max reverse standoff voltage and ±15kV IEC 61000-4-2 ESD protection. |
| 3 | VP | power_in | Positive rail of the diode-steering array, connected to the supply or positive reference of the protected interface (reverse standoff voltage 5.5V max). |
| 4 | VN | power_in | Negative rail of the diode-steering array, connected to ground (GND) as the reference for I/O capacitance and leakage specifications. |
