TT0501SDX from Shenzhen JingYang, in a SOD-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 | Bidirectional TVS terminal for one high-speed data line, rated for a 5.0 V reverse working voltage (VRWM) and about 0.3 pF typical capacitance between I/O_1 and I/O_2. |
| 2 | I/O_2 | passive | Bidirectional TVS terminal for one high-speed data line, rated for a 5.0 V reverse working voltage (VRWM) and about 0.3 pF typical capacitance between I/O_2 and I/O_1. |
