AMUR1030DC-HF

Overview

The AMUR1030DC-HF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for ESD protection in high-speed data lines. It features a 30V working voltage and a peak pulse power dissipation of 3kW. The device utilizes an axial R6 package and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a breakdown voltage of 41.7V and a maximum clamping voltage of 68.2V at a peak pulse current of 43.9A.

Feature Summary

• Provides robust transient voltage suppression for sensitive electronic circuits against electrostatic discharge events.
• Engineered with low capacitance characteristics suitable for protecting high-speed data interfaces.
• Constructed with axial leaded packaging to facilitate through-hole mounting on printed circuit boards.

Applications

• Protection of USB 2.0 and USB 3.0 ports from electrostatic discharge.
• Guarding HDMI and DisplayPort interfaces against voltage transients.
• Shielding Ethernet data lines from ESD events in network equipment.

Procurement Notes

Verify the specific datasheet version for the AMUR1030DC-HF to confirm exact capacitance values and pin configurations before integration. Ensure that the axial R6 package dimensions align with the target PCB footprint. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors, as regulatory certifications can vary by production batch.

Selection Notes

Select this component when designing circuits requiring unidirectional TVS protection for 30V data lines. The axial R6 package is appropriate for applications where surface space is less constrained than in compact mobile devices. Evaluate the peak pulse current capability against expected surge levels to ensure adequate safety margins during transient events.
