• Surge protection for data lines in communication equipment
• Overvoltage protection for I/O interfaces in industrial automation systems
• Protection for automotive electronics (ECUs, sensors)
• Safeguarding consumer electronics from voltage transients

Features

• Low clamping voltage for efficient transient suppression
• Low capacitance to preserve signal integrity in high-speed circuits
• Compact surface-mount package for space-saving PCB designs
• Compliant with industry ESD protection standards (IEC 61000-4-2)
• Lead-free and RoHS compliant for environmental responsibility

Benefits

• Increased product reliability by preventing damage from voltage transients.
• Maintained data integrity in high-speed applications thanks to low capacitance.
• Enables smaller and more compact product designs.
• Adherence to environmental standards for sustainable products.
• Reduced warranty costs and field failures associated with ESD damage.

Technical Specifications

The DF5A5.6CFU features a reverse standoff voltage of 5.6V. Its design is optimized for handling ESD events, as specified by industry standards. The clamping voltage is kept low to ensure that protected circuits are not exposed to harmful voltage levels during transient events. It is supplied in a small surface-mount package (e.g., SOD-962) for easy and automated assembly. The operating temperature range is typically -40°C to +85°C. This diode can withstand repeated ESD strikes without any significant performance degradation.
