ECLAMP2398P.TCT

Overview

The ECLAMP2398P.TCT is an eight-channel low-pass LC filter array with integrated transient voltage suppression diodes, designed for color LCD data lines. It utilizes Pi-network topology to suppress EMI/RFI and electrostatic discharge. Key electrical parameters include a 5 V operating voltage, 6 V breakdown voltage, and 12 pF diode capacitance per channel. The device offers high protection ratings of 15 kV contact and 20 kV air gap ESD withstand. It operates within a temperature range of -40°C to +85°C and is housed in a compact DFN-4016-16 package.

Feature Summary

• Integrates low-pass filtering and TVS protection in a single component
• Provides bidirectional signal line protection against ESD and EMI
• Utilizes Pi-network LC topology for superior noise attenuation

Applications

• Color LCD interface protection in mobile devices
• Data line shielding in portable electronics
• EMI suppression for display interfaces

Procurement Notes

Verify the specific suffix 'TCT' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the DFN-4016-16 footprint matches your PCB layout requirements. Check for any recent product change notifications that may affect pinout or materials. Validate that the 5V operating voltage aligns with your system's signal levels.

Selection Notes

Select this component when both EMI filtering and ESD protection are required for multi-line displays. The 12 pF capacitance supports high-speed data transmission without significant signal degradation. The bidirectional polarity suits differential or AC-coupled signals. Consider the 16-pin exposed pad for thermal dissipation and grounding efficiency in dense layouts.

Part Context

Part of Semtech's EClamp series, which combines passive filtering with active clamping. This family targets high-density consumer electronics where space is limited. The ECLAMP2398P specifically addresses the needs of color LCD interfaces requiring robust interference rejection. It replaces discrete LC filters and separate TVS arrays, simplifying BOM management.

Replacement Considerations

ECLAMP2378K.TCT is a related 8-channel variant but features different capacitance (20pF) and package dimensions (DFN-3313-16). Verify pin compatibility before substitution. No direct identical replacement is confirmed in public data.
