Breaking the Bottleneck of Ultra-High-Speed Signals — Introducing the New ESD/EOS Protection Weapon

In an era where high-speed interfaces like USB4, Thunderbolt 4, and PCIe 5 are operating at full throttle, are you still relying on traditional TVS protection? You might not realize it, but those familiar protection devices have quietly become obstacles that limit signal performance.

The ESD/EOS protection expert tailor-made for high-speed interfaces

The newly launched AZ5BFS-01M from Amazing is an ultra-low capacitance ESD protection device specifically designed for next-generation high-speed signal interfaces. Key features include:

• Only 0.25 dB Insertion Loss @10 GHz — Maintain signal integrity without compromise in high-performance applications
• Ultra-low Capacitance of Just 0.18 pF — Significantly reduces signal interference risk
• MCSP 0201 Package (0.63 mm × 0.33 mm × 0.25 mm) — Ultra-compact size saves PCB space, ideal for ultra-thin devices and dense layouts
• Compliant with IEC 61000-4-2 Level 4 — ±15 kV air discharge / ±9 kV contact discharge, perfect for daily challenges in USB4/Type-C applications

Why are traditional TVS devices killing high-speed signals?

In signal speeds exceeding 10 to 20 Gbps, such as USB4 and Thunderbolt 4, the insertion loss (S21) of TVS diodes causes serious harmonic distortion at GHz-level frequencies, leading to:

• RF signal degradation (SNR loss)
• System-level wireless de-sense
• High-speed communication protocol test failures

These issues directly impact system yield and user experience, especially in USB-C environments that integrate power and data, where even minor signal degradation can lead to critical failures.

How does the AZ5BFS-01M solve the problem?

With its exceptionally low insertion loss (0.25 dB @ 10 GHz) and advanced snapback-triggered clamping technology, the AZ5BFS-01M ensures clean high-speed signal transmission while delivering robust transient suppression. Its applications include:

• USB4/Type-C port protection
• Thunderbolt 3/4 data lines and connectors
• PCIe Gen4 / Gen5 high-speed links
• High-end laptops, workstations, and AIoT devices

Even more importantly, the AZ5BFS-01M can be deployed directly near the connector port, accelerating ESD response and avoiding long trace-induced interference with protective performance.

Conclusion: Are you ready for the guardian of next-gen high-speed devices?

The AZ5BFS-01M is not just compact — it's powerful. In today’s world of ever-increasing data throughput, choosing the right protection device is key to unleashing your product’s full potential and ensuring it passes both user and market tests.
