ESD9B5.0ST5G

The ESD9B5.0ST5G is a 5.0V ESD protection diode designed to safeguard sensitive electronics from electrostatic discharge (ESD) and transient voltage events. Key features include:
- Low clamping voltage for effective protection.
- Ultra-low capacitance (~0.5pF typical) to minimize signal distortion in high-speed circuits.
- Bi-directional operation, suitable for both positive and negative voltage spikes.
- Compact SOD-523 (SC-79) package, ideal for space-constrained applications.
Commonly used in USB ports, HDMI interfaces, and high-frequency data lines, it ensures robust ESD protection (IEC 61000-4-2 Level 4: ±8kV contact, ±15kV air discharge).
This diode is optimized for high-speed data lines (e.g., USB 3.0, Ethernet) where signal integrity is critical.
