Latest company news about Breaking the bottleneck of ultra high speed signals - launching a new ESD/EOS protection tool

In the era of high-speed interfaces such as USB4, Thunderbolt 4, and PCIe 5 running at full speed, are you still relying on traditional TVS protection? You may not have realized that these familiar protective devices have quietly become an obstacle, limiting signal performance.

ESD/EOS protection experts tailored for high-speed interfaces
Amazing's latest AZ5BFS-01M is an ultra-low capacitance ESD protection device designed specifically for the next generation of high-speed signal interfaces. The main functions include:

The insertion loss at 10 GHz is only 0.25 dB - ensuring uncompromising signal integrity in high-performance applications
Ultra low capacitance, only 0.18 pF - greatly reducing the risk of signal interference
MCSP 0201 Package (0.63 mm × 0.33 mm × 0.25 mm) - Ultra small size saves PCB space and is an ideal choice for ultra-thin devices and dense layouts
Compliant with IEC 61000-4-2 Level 4 standard - ± 15 kV air discharge/± 9 kV contact discharge, it can perfectly meet the daily challenges in USB4/Type-C applications

Why do traditional TVS devices severely restrict high-speed signals?
When signal speeds such as USB4 and Thunderbolt 4 exceed 10 to 20 Gbps, the insertion loss (S21) of TVS diodes can cause severe harmonic distortion in the GHz frequency band, resulting in distortion:

RF signal attenuation (SNR loss)
System level wireless sensitivity decreases
High speed communication protocol test failure
These issues will directly affect system productivity and user experience, especially in USB-C environments that integrate power and data, where even minor signal attenuation can lead to serious malfunctions.

How does AZ5BFS-01M solve the problem?
With its extremely low insertion loss (0.25 dB at 10 GHz) and advanced bounce trigger clamp technology, AZ5BFS-01M ensures pure high-speed signal transmission while providing powerful transient suppression capabilities. Its applications include:

USB4/Type-C port protection
Thunderbolt 3/4 data cable and connector
PCIe Gen4/Gen5 high-speed link
High end laptops, workstations, and artificial intelligence IoT devices
More importantly, AZ5BFS-01M can be directly installed near the connector port, thereby accelerating ESD response speed and avoiding interference from long wires on protection performance.
