SVC371R-TL-E

Overview

The SVC371R-TL-E is a silicon TVS diode manufactured by onsemi, designed for transient voltage suppression in electronic circuits. It features a bidirectional configuration suitable for protecting sensitive data lines and communication interfaces from electrostatic discharge (ESD) and other transient events. The component is housed in an SOD-323 surface-mount package, providing a compact footprint for high-density PCB layouts. Key electrical characteristics include a standoff voltage of 3.3V and a maximum clamping voltage defined under specific pulse current conditions, ensuring reliable protection without disrupting normal signal operation.

Feature Summary

• Bidirectional transient voltage suppression capability for balanced line protection
• Low capacitance design to maintain signal integrity in high-speed data applications
• Robust ESD protection performance compliant with IEC 61000-4-2 standards
• Compact SOD-323 surface-mount package for space-constrained designs

Applications

• Protection of USB 2.0 and USB 3.0 data lines
• ESD protection for HDMI and DisplayPort interfaces
• Transient suppression in mobile phone and portable device circuits
• Signal line protection in industrial communication modules

Procurement Notes

Verify the manufacturer marking code and date code on the component body to confirm authenticity. Ensure the ordering suffix matches the required tape-and-reel packaging specification. Cross-reference the part number with the official onsemi datasheet to confirm pinout orientation and thermal specifications before integration into the production supply chain.

Selection Notes

Select this component when bidirectional protection is required for low-voltage differential signaling lines. Evaluate the peak pulse power dissipation requirements against the expected transient energy levels in the target application. Consider the junction capacitance value to ensure it does not degrade the bandwidth or signal quality of the protected interface compared to alternative unidirectional devices.

Part Context

This device belongs to onsemi's series of surface-mount transient voltage suppressors aimed at consumer electronics and telecommunications markets. It complements unidirectional variants within the same product family, offering symmetrical clamping for AC or differential signals. The SOD-323 form factor aligns with industry trends for miniaturization in portable and handheld electronic equipment.

Replacement Considerations

Check for direct equivalents from manufacturers such as Littelfuse or Bourns offering similar standoff voltages and package types. Verify that any substitute maintains identical bidirectional functionality and meets the same IEC 61000-4-2 ESD immunity levels. Confirm mechanical compatibility including lead pitch and soldering profile requirements.
