**Shenzhen JingYang** · ESD And Surge Protection (TVS/ESD) · SOT-563

TT0515THX from Shenzhen JingYang, in a SOT-563. 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 | bidirectional | Protected high-speed data line with a TVS clamp to GND; typical capacitance is 0.6pF (0.8pF maximum) between I/O and GND at 0V, 1MHz, and the working voltage is 3.3V. |
| 2 | GND | power_in | Common ground reference for the TVS clamps; all I/O pins clamp to this pin. |
| 3 | I/O_2 | bidirectional | Protected high-speed data line with a TVS clamp to GND; typical capacitance is 0.6pF (0.8pF maximum) between I/O and GND at 0V, 1MHz, and the working voltage is 3.3V. |
| 4 | I/O_3 | bidirectional | Protected high-speed data line with a TVS clamp to GND; typical capacitance is 0.6pF (0.8pF maximum) between I/O and GND at 0V, 1MHz, and the working voltage is 3.3V. |
| 5 | I/O_4 | bidirectional | Protected high-speed data line with a TVS clamp to GND; typical capacitance is 0.6pF (0.8pF maximum) between I/O and GND at 0V, 1MHz, and the working voltage is 3.3V. |
| 6 | I/O_5 | bidirectional | Protected high-speed data line with a TVS clamp to GND; typical capacitance is 0.6pF (0.8pF maximum) between I/O and GND at 0V, 1MHz, and the working voltage is 3.3V. |
