Présentation
Description
- Bidirectional clamping for positive/negative voltage spikes.
- Low clamping voltage (typ. 9.2V at 5A) for robust protection.
- High surge current handling (30A peak, 8/20µs pulse).
- Ultra-low capacitance (~3pF per line) to minimize signal distortion.
- IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) compliance.
Commonly used in USB ports, HDMI, Ethernet, and other high-speed data lines, it safeguards against ESD, lightning surges, and other transients. Packaged in a SOT-23-6 form factor, it’s ideal for space-constrained designs.
For detailed specs, refer to the datasheet from manufacturers like Littelfuse or ON Semiconductor.
Features
- Voltage Rating: 30V working voltage.
- Low Clamping: Effective surge protection with low clamping voltage.
- Bidirectional: Protects against positive and negative transients.
- Low Capacitance: Typically 0.5pF (max 1pF), ideal for high-speed data lines (USB, HDMI, etc.).
- ESD Protection: Meets IEC 61000-4-2 (Level 4: ±30kV air/contact).
- Compact Package: SOT-23-6 for space-constrained designs.
- Low Leakage: Ensures minimal power loss.
Ideal for consumer electronics, automotive, and industrial applications requiring robust transient protection without signal degradation.
Pinout
- Pin Count: 6 (typically in a SOT-23-6 package).
- Functions:
- Protects two signal lines (e.g., USB, HDMI) from ESD, surges, and transients.
- Bidirectional clamping for positive/negative voltage spikes.
- Low capacitance (~3pF per line) for minimal signal distortion.
- Supports IEC 61000-4-2 (ESD) up to ±30kV.
Common applications include USB 2.0, audio ports, and other high-speed data lines.
