TT0501MCX

Shenzhen JingYang · ESD And Surge Protection (TVS/ESD) · SOD-923

TT0501MCX from Shenzhen JingYang, in a SOD-923. 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 I/O_1 is one terminal of the bidirectional TVS, rated for ±30kV IEC 61000-4-2 air and contact ESD, with VRWM of 5.0V and typical parasitic capacitance of 15pF.
2 I/O_2 passive I/O_2 is the other terminal of the bidirectional TVS, protecting the single data line between I/O_1 and I/O_2 with a typical leakage of 0.1μA at 5V.
