In modern automotive electronics and industrial control systems, safeguarding high-speed data interfaces from electrostatic discharge (ESD) and transient voltage events is essential. Amazing Microelectronic introduces two advanced TVS (Transient Voltage Suppression) diodes designed for these challenges: AZ9400-01F and AZ9400-02S. 

Key Features of AZ9400 Series TVS Devices 

AZ9400-01F 

• Ultra-small 0402 package for space-constrained PCB designs. 

• Protects one channel of bidirectional signal line. 

• Proprietary clamping cells with ultra-low capacitance, ensuring signal integrity for high-speed data lines. 

• Ideal for automotive Ethernet and industrial communication systems. 

AZ9400-02S 

• Popular SOT23-3L package, widely adopted in the automotive industry. 

• Protects two channels of bidirectional lines. 

• Proprietary clamping cells for robust transient voltage protection. 

• Specifically designed for high-speed automotive Ethernet interfaces. 

Applications 

The AZ9400 series is engineered for demanding environments, including: 

• Automotive network protection:  

• OPEN Alliance IEEE 100BASE-T1 / 1000BASE-T1 Ethernet 

• Automotive backbone communications 

• Gateway and infotainment systems 

• Industrial control systems 

• High-speed data transmission lines 

Why Choose AZ9400 Series TVS Diodes?
