TT1211MBX

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

TT1211MBX 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 bidirectional Protected data, control or power line; the TVS clamps transients on this line with a nominal reverse working voltage VRWM of 12.0V, typical capacitance of 10pF (15pF maximum) and ESD rating of ±25kV air / ±17kV contact per IEC 61000-4-2.
2 GND power_in Ground reference for the TVS; the datasheet gives forward voltage VF of 0.7V to 1.2V between GND and I/O at IT = 1mA.
