TT0514VLX

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

TT0514VLX 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 bidirectional Data line I/O with TVS protection, rated 5.0 V nominal reverse working voltage with 0.1 µA typical leakage at VRWM, and withstands over 1000 ESD strikes at ±8 kV contact discharge.
2 GND power_in Negative reference pin that should connect to the PCB GND, with the connection kept as short as possible to minimize parasitic inductance.
3 I/O_3 bidirectional Data line I/O with TVS protection, rated 5.0 V nominal reverse working voltage with 0.1 µA typical leakage at VRWM, and withstands over 1000 ESD strikes at ±8 kV contact discharge.
4 I/O_4 bidirectional Data line I/O with TVS protection, rated 5.0 V nominal reverse working voltage with 0.1 µA typical leakage at VRWM, and withstands over 1000 ESD strikes at ±8 kV contact discharge.
5 VCC power_in Connects to the PCB VCC rail through a wide, short connection to limit parasitic inductance; the datasheet gives no VCC voltage limit for this pin.
6 I/O_2 bidirectional Data line I/O with TVS protection, rated 5.0 V nominal reverse working voltage with 0.1 µA typical leakage at VRWM, and withstands over 1000 ESD strikes at ±8 kV contact discharge.
