UCLAMP2611ZA.F

Overview

The UCLAMP2611ZA.F is a unidirectional transient voltage suppressor (TVS) diode from Semtech's uClamp series, designed for electrostatic discharge (ESD) protection. It features a single-channel configuration with a working voltage of 26V and a breakdown voltage of 28.9V. The device utilizes solid-state silicon avalanche technology to provide fast response times and low clamping voltages without degradation. Packaged in an ultra-small SLP0603P2T footprint measuring 0.6 x 0.3 x 0.35mm, it offers low leakage current and high ESD withstand capability compliant with IEC 61000-4-2 standards.

Feature Summary

• Provides board-level transient protection against ESD events using solid-state silicon avalanche technology
• Features an ultra-small surface-mount package optimized for space-constrained portable electronics
• Delivers low operating and clamping voltages with minimal leakage current for signal integrity
• Designed to replace multilayer varistors while offering superior electrical characteristics

Applications

• Protection of sensitive data lines in cellular phones and mobile devices
• ESD suppression for USB interfaces and peripheral connections
• Surge protection in portable digital cameras and MP3 players
• Guarding I/O ports in notebook computers and PDAs

Procurement Notes

Verify the specific suffix ZA.F against the manufacturer datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment due to the small SLP0603P2T package dimensions. Confirm RoHS compliance status for your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when protecting single high-speed or power lines requiring a 26V working voltage. The unidirectional polarity suits applications where signal polarities remain above ground. Consider the ultra-small form factor for dense PCB layouts where traditional TVS arrays are impractical. Evaluate capacitance requirements if signal frequency is critical, though specific values are not provided in the summary.

Part Context

This part belongs to Semtech's uClamp series, which focuses on replacing bulky multilayer varistors with compact solid-state solutions. The series targets portable consumer electronics needing robust ESD immunity within tight spatial constraints. The UCLAMP2611ZA.F specifically addresses higher voltage line protection compared to lower-voltage variants in the same family.

Replacement Considerations

Check Semtech documentation for direct cross-references such as UCLAMP2611Z. Verify that substitute parts maintain the same unidirectional characteristic and SLP0603P2T package dimensions to ensure mechanical fit.
