TT0502PFX from Shenzhen JingYang, 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/O_1 | passive | Protected bidirectional high-speed data line 1, with 5.0pF typical I/O-to-I/O capacitance and 5.0V reverse working voltage. |
| 2 | I/O_2 | passive | Protected bidirectional high-speed data line 2, with 5.0pF typical I/O-to-I/O capacitance and 5.0V reverse working voltage. |
| 3 | GND | power_in | Ground reference pin of the two-line TVS array (SOT-523 top view). |
