# TT0514TLX

**Shenzhen JingYang** · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

TT0514TLX from Shenzhen JingYang, in a SOT-23-6L. 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 high-speed data line I/O clamped to GND, with 5.0 V nominal reverse working voltage (VRWM) and 0.1 μA typical leakage at VRWM. |
| 2 | GND | power_in | Negative reference pin that must connect to the PCB GND, with the connection kept as short as possible to minimize parasitic inductance. |
| 3 | I/O_2 | passive | Protected high-speed data line I/O clamped to GND, with 5.0 V nominal reverse working voltage (VRWM) and 0.1 μA typical leakage at VRWM. |
| 4 | I/O_4 | passive | Protected high-speed data line I/O clamped to GND, with 5.0 V nominal reverse working voltage (VRWM) and 0.1 μA typical leakage at VRWM. |
| 5 | VCC | power_in | Supply-side reference pin of the TVS array, connected to the PCB VCC through wide vias as the datasheet layout guideline requires. |
| 6 | I/O_3 | passive | Protected high-speed data line I/O clamped to GND, with 5.0 V nominal reverse working voltage (VRWM) and 0.1 μA typical leakage at VRWM. |
