TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-143
TPD2E001DZDR 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 | GND | power_in | Ground reference for the TVS diode array, connected to the common node of the steering diodes. |
| 2 | I/O1 | passive | ESD-protected I/O line 1, rated for ±16kV air and ±10kV contact discharge (IEC 61000-4-2) with 1.5pF max capacitance. |
| 3 | I/O2 | passive | ESD-protected I/O line 2, rated for ±16kV air and ±10kV contact discharge (IEC 61000-4-2) with 1.5pF max capacitance. |
| 4 | VCC | power_in | Positive supply/reference rail for the steering diodes, with working peak reverse voltage of 5.5V max. |
