TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23
TPCM1213A-01SO from TECH PUBLIC, in a SOT-23. 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 | Protected channel input (CH1) of the TVS array, rated for IEC 61000-4-2 ±15kV air and ±8kV contact discharge, with DC voltage limited to (VN − 0.5) to (VP + 0.5) V. |
| 2 | VP | power_in | Positive supply/reference rail of the diode array, with operating supply voltage typically 3.3 V and 5.5 V maximum, and VP − VN absolute maximum of 6.0 V. |
| 3 | VN | power_in | Negative reference rail of the diode array, normally connected to ground (0 V), with VP − VN absolute maximum of 6.0 V. |
