ECLAMP2504K.TCT

Overview

The ECLAMP2504K.TCT is a bidirectional transient voltage suppression diode and LC EMI filter array manufactured by Semtech. It features four channels with a working voltage of 5 V, packaged in an 8-UFDFN Exposed Pad (DFN-3030-16) format. Key electrical parameters include a breakdown voltage of 6 V, a clamp voltage of 15 V, and a peak pulse current rating of 5 A. The device offers a capacitance of 12 pF per channel, providing effective electrostatic discharge protection rated at 12 kV contact and 18 kV air gap.

Feature Summary

• Integrates ESD protection with third-order low-pass LC filtering for simultaneous signal integrity and circuit safety
• Provides bidirectional transient voltage suppression to protect sensitive data lines from polarity-independent surges
• Utilizes a compact DFN package design optimized for high-density surface-mount assembly

Applications

• High-speed data line protection in automotive infotainment systems
• ESD mitigation for USB interface circuits
• Signal conditioning for industrial control data buses

Procurement Notes

Verify the specific suffix 'TCT' indicates tape-and-reel packaging configuration when sourcing. Confirm the manufacturer part number matches Semtech Corporation documentation exactly. Ensure the component meets RoHS compliance requirements as specified in official datasheets. Cross-reference the DFN-3030-16 footprint dimensions against PCB layout guidelines prior to procurement.

Selection Notes

Select this component for applications requiring combined ESD protection and EMI filtering on 5 V data lines. The bidirectional nature suits AC-coupled or differential signaling where voltage polarity may reverse. Evaluate the 12 pF capacitance against maximum signal frequency requirements to ensure minimal insertion loss. Verify that the 15 V clamp voltage remains below the downstream IC's absolute maximum rating.

Part Context

This device belongs to the Semtech ECLAMP series, which specializes in system-level ESD and EMI protection solutions. The series targets automotive and industrial markets, offering integrated filtering capabilities alongside standard TVS functions. These components are designed to replace discrete protection arrays, reducing board space and simplifying supply chain management for complex electronic assemblies.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic TVS diodes lack the integrated LC filtering characteristics. Ensure any replacement maintains the 8-UFDFN Exposed Pad footprint and 5 V operating voltage specification.
