ECLAMP2455K.TCT

Overview

The ECLAMP2455K.TCT is a third-order low-pass RC (Pi) filter array with integrated transient voltage suppression diodes, manufactured by Semtech Corporation. Designed for color LCD interface protection, it operates at a working voltage of 5 V and features bidirectional polarity across three channels. The device utilizes an 8-UFDFN exposed pad package (SLP1713P8) measuring 1.70 mm x 1.30 mm. Key electrical parameters include a breakdown voltage of 6 V, a diode capacitance of 24 pF, and ESD protection ratings of 8 kV contact discharge and 15 kV air gap discharge. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates RC low-pass filtering with TVS diodes for simultaneous EMI suppression and electrostatic discharge protection
• Provides bidirectional signal line protection suitable for high-speed data interfaces
• Utilizes a compact surface-mount footprint designed for space-constrained portable electronics

Applications

• Color LCD interface protection in mobile devices
• ESD and EMI suppression for display data lines
• Portable electronic equipment signal conditioning

Procurement Notes

Verify the specific suffix K against the manufacturer's current datasheet to confirm component specifications, as suffixes often denote tolerance or packaging variations. Ensure the ordering code matches the required tape-and-reel or cut-tape configuration. Cross-reference the 8-UFDFN package dimensions with PCB footprints to prevent assembly errors. Confirm RoHS compliance status through official documentation before integration into regulated products.

Selection Notes

Select this component when both EMI filtering and ESD protection are required on a single channel. The 24 pF capacitance supports moderate-speed signals without excessive attenuation. Compare channel count and package size against alternatives like the ECLAMP2454PTCT if more lines or different form factors are needed. Ensure the 5 V operating voltage aligns with the target circuit logic levels.

Part Context

This part belongs to the Semtech EClamp family of protection products. These devices combine passive filtering elements with active clamping structures to address complex interference issues in digital video and data transmission paths. The EClamp series is widely used in consumer electronics to meet stringent electromagnetic compatibility standards while maintaining signal integrity.
