ESD9X12ST5G

The ESD9X12ST5G is a low-capacitance TVS diode array designed for ESD protection in high-speed data lines, such as USB, HDMI, and Ethernet. Key features include:
- Ultra-low capacitance (~0.5pF per line) to minimize signal distortion.
- Robust ESD protection (IEC 61000-4-2, ±30kV contact/air discharge).
- Small DFN-10 package for space-constrained designs.
- Bidirectional clamping for positive/negative transients.
Ideal for high-speed interfaces (USB 3.0, DisplayPort, etc.), it ensures signal integrity while safeguarding sensitive ICs from electrostatic discharge.
