ESD9B3.3ST5G

The ESD9B3.3ST5G is a 3.3V bidirectional ESD protection diode designed to safeguard sensitive electronics from electrostatic discharge (ESD) and transient voltage spikes. Key features include:
- Low clamping voltage for robust protection (IEC 61000-4-2 Level 4: ±8kV contact, ±15kV air discharge).
- Ultra-low capacitance (~0.5pF typical) to minimize signal distortion in high-speed circuits (e.g., USB, HDMI).
- Bidirectional operation, making it suitable for both positive and negative voltage swings.
- Small DFN-2L package (1.0 × 0.6mm) for space-constrained PCBs.
Ideal for high-speed data lines, ports, and IC protection in consumer electronics, IoT, and automotive applications. Its fast response time (<1ns) ensures quick suppression of ESD events.
For detailed specs, refer to the manufacturer’s datasheet.

The ESD9B3.3ST5G is a 5-pin ESD protection diode designed for safeguarding low-voltage circuits.
Pin Functions:
1. Pin 1 (Anode 1): Connects to the protected line (e.g., data or signal line).
2. Pin 2 (Anode 2): Second protected line (bidirectional protection).
3. Pin 3 (GND): Ground connection.
4. Pin 4 (Anode 3): Third protected line (if applicable).
5. Pin 5 (Cathode): Common cathode tied to ground.
Key Features:
- Voltage Rating: 3.3V (clamping voltage).
- Low Capacitance: ~3pF (minimizes signal distortion).
- Bidirectional Protection: Guards against positive/negative ESD spikes (e.g., IEC 61000-4-2).
Applications: USB, HDMI, or other high-speed interfaces requiring ESD protection.
