TPE0552R3 from TECH PUBLIC, in a SOT-523. 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/O1 | passive | Protected line 1 of the 2-line bi-directional TVS, with reverse working voltage 5V max and breakdown 6.5V min to 8.5V max at 1mA, connected through the diode to pin 3. |
| 2 | I/O2 | passive | Protected line 2 of the 2-line bi-directional TVS, with reverse working voltage 5V max and breakdown 6.5V min to 8.5V max at 1mA, connected through the diode to pin 3. |
| 3 | COMMON | passive | Common node of the two TVS diode branches (top pin in the diagram), with junction capacitance to pins 1 and 2 of 15pF typ and 20pF max at 0V, 1MHz. |
