TPGBLC03C from TECH PUBLIC, in a SOD-323. 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 | I/O 1 | passive | Terminal 1 of the bi-directional TVS diode, connected to the protected power or data line; the diagram shows the device as symmetric, with VRWM 3.3 V max and ±30 kV ESD (air and contact) per IEC 61000-4-2. |
| 2 | I/O 2 | passive | Terminal 2 of the bi-directional TVS diode, connected to the return or ground side of the protected line; the device is symmetric, so polarity does not matter, with VBR 4 V min to 6 V max at 1 mA. |
