Core Features & Advantages
The ESD204DQAR delivers 4-channel bidirectional ESD and surge protection with ultra-low 0.55pF capacitance, supporting up to 6Gbps high-speed interfaces (HDMI 2.0, USB 3.0) while clamping at only 8.5V under 5.5A surge.
- Primary Function: 4-channel bidirectional TVS ESD protection diode array for high-speed differential and single-ended interfaces up to 6Gbps, providing IEC Level 4 ESD and 5.5A surge protection.
- Advantages:
- Ultra-low 0.55pF channel capacitance — preserves signal integrity on HDMI 2.0 (6Gbps) and USB 3.0 (5Gbps) differential pairs with minimal eye-diagram degradation.
- ±30kV IEC 61000-4-2 Level 4 ESD rating — maximum ESD protection level without external TVS, surviving the harshest electrostatic discharge environments.
- Low 8.5V clamping at 5.5A surge — tight clamping voltage protects downstream ICs with 3.3V or lower absolute maximum ratings during IEC 61000-4-5 surge events.
Typical Application Scenarios
- Industry: Consumer / Computing / Networking
- Equipment: DVR/NVR, laptops, desktops, set-top boxes, TVs, monitors, Ethernet switches
- Use Cases:
- HDMI 2.0 port ESD and surge protection on 4 differential pairs with 0.55pF capacitance preserving 6Gbps eye diagram compliance.
- USB 3.0 SuperSpeed port protection (TX/RX differential pairs) with flow-through routing in 2.5 x 1mm USON package.
- DisplayPort 1.3 and Gigabit Ethernet (1000BASE-T) connector protection with ±30kV contact discharge rating.
