EMC5DXV5T1

Overview

The onsemi EMC5DXV5T1 is a quad-channel ESD protection device designed for high-speed data lines. It features a unidirectional configuration with a 5 V operating voltage, housed in a compact SC-74-6 (SOT-457-6) surface-mount package. The component provides robust transient suppression with a peak pulse power dissipation of 350 W and a maximum clamping voltage of 15.5 V. Key electrical characteristics include a breakdown voltage of 6 V, a peak pulse current rating of 23 A, and a low diode capacitance of 400 pF to minimize signal distortion. It offers electrostatic discharge protection up to 8 kV (contact) and 15 kV (air), operating reliably within a temperature range of -55 °C to +150 °C.

Feature Summary

• Quad-channel architecture for simultaneous multi-line protection
• Low capacitance design suitable for high-speed data interfaces
• High energy handling capability for severe transient events
• Compact footprint for space-constrained PCB layouts

Applications

• Portable electronics such as smartphones and tablets
• Universal Serial Bus (USB) port protection
• High-definition multimedia interface (HDMI) circuits
• Industrial control systems requiring ESD mitigation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to integration into production assemblies. Cross-reference the active status with current distributor availability to mitigate supply chain risks during long-term manufacturing cycles.

Selection Notes

Select this component when designing circuits that require protection for multiple differential or single-ended high-speed lines within a limited board area. The 400 pF capacitance value is critical for maintaining signal integrity in applications exceeding standard USB 2.0 speeds. Ensure the system's expected transient energy levels remain below the 350 W peak pulse power rating to guarantee device longevity and reliable operation under stress conditions.

Part Context

This device belongs to the EMC5DX series of ESD suppressors from onsemi, engineered specifically for consumer and industrial electronics. It addresses the growing demand for compact, multi-channel protection solutions in modern portable devices. The series integrates advanced silicon technology to provide superior clamping performance compared to discrete diode arrangements, simplifying bill-of-materials and assembly processes for OEMs.

Replacement Considerations

Evaluate alternative quad-channel TVS arrays from onsemi or other manufacturers with matching SC-74-6 footprints. Verify that substitute components maintain equivalent capacitance values below 500 pF and meet the same 5 V operating voltage requirements. Ensure thermal resistance and peak pulse power ratings are sufficient for the target application's environmental conditions.
