UCLAMP1311ZATFT

Overview

The UCLAMP1311ZATFT is a unidirectional transient voltage suppression diode from Semtech's UCLAMP series, designed for high-speed data line protection. It features a working voltage of 13 V and a low capacitance of 19 pF, ensuring minimal signal distortion in high-frequency applications. The device offers robust electrostatic discharge protection with contact voltages up to 30 kV and air gap voltages up to 30 kV. Packaged in an SLP0603P2X3H footprint, it provides efficient surface-mount integration for compact circuit designs requiring reliable surge suppression.

Feature Summary

• Provides bidirectional ESD and surge protection for single high-speed data lines
• Maintains low capacitance to preserve signal integrity in high-frequency interfaces
• Delivers high clamping capability with specified peak pulse current handling

Applications

• Protection for USB 3.0 and USB 2.0 data lines
• ESD shielding for HDMI and DisplayPort interfaces
• Surge protection for high-speed serial communication buses

Procurement Notes

Verify the specific suffix 'ATFT' against the manufacturer's official datasheet to confirm tape and reel specifications and marking codes. Ensure the selected component matches the required SLP0603P2X3H package dimensions for PCB layout compatibility. Cross-reference the RoHS compliance status with the latest environmental declaration documents provided by Semtech before finalizing procurement orders.

Selection Notes

Select this component when protecting single-ended high-speed lines requiring 13 V operating voltage. The 19 pF capacitance makes it suitable for interfaces sensitive to signal degradation. Compare peak pulse power ratings against expected surge environments to ensure adequate safety margins. Verify that the unidirectional configuration aligns with the circuit's polarity requirements.

Part Context

This part belongs to Semtech's UCLAMP family of ultra-small ESD suppressors. These devices are engineered for portable electronics and high-speed digital interfaces where space constraints and signal integrity are critical. The series complements other Semtech protection solutions like RCLAMP for different voltage and channel configurations.

Replacement Considerations

Check Semtech's official substitution guide for direct replacements within the UCLAMP series. Consider UCLAMP3311ZVTFT for lower voltage applications. Verify pinout and package compatibility before substituting with generic TVS diodes.
