**Shenzhen JingYang** · ESD And Surge Protection (TVS/ESD) · DFN1006-2L

TT0501VBX from Shenzhen JingYang, in a DFN1006-2L. 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 | Bidirectional TVS/ESD protection terminal for one high-speed data, control or power line, rated for a nominal reverse working voltage of 5.0 V with 2.0 pF maximum parasitic capacitance between I/O_1 and I/O_2. |
| 2 | I/O_2 | bidirectional | Bidirectional TVS/ESD protection terminal paired with I/O_1, with 1.0 mA reverse breakdown test current giving 6.0 V to 9.0 V breakdown and 1.0 µA maximum reverse leakage at 5 V. |
