UCLAMP3611ZVTFT

Overview

The UCLAMP3611ZVTFT is a bidirectional transient voltage suppression diode from Semtech’s SurgeSwitch family, designed for ultra-small footprint applications. It features a 3.6 V working voltage and a 3.8 V breakdown voltage within an SLP1006P (0402) package. The device provides a clamping voltage of 7.3 V and handles a peak pulse current of 80 A with a peak pulse power dissipation of 580 W. It offers electrostatic discharge protection up to 30 kV via air gap and contact discharge. Operating temperatures range from -55°C to +85°C.

Feature Summary

• Ultra-compact SLP1006P surface-mount package design
• Bidirectional polarity configuration for signal line protection
• High-energy surge handling capability at 580 W
• Robust ESD immunity rated at 30 kV air gap

Applications

• Protection of high-speed data lines in portable electronics
• ESD suppression for USB and HDMI interfaces
• Surge protection in mobile communication devices
• Signal line conditioning in consumer IoT hardware

Procurement Notes

Verify the specific ordering suffix ZVTFT to confirm the tape-and-reel packaging quantity and variant designation. Ensure the component matches the required 3.6 V working voltage specification for the target circuit. Confirm that the SLP1006P package dimensions align with the PCB land pattern requirements. Check RoHS compliance status if restricted substances are mandated by the end product regulations.

Selection Notes

Select this component when space constraints necessitate an 0402 form factor while requiring high surge robustness. The 3.6 V rating suits single-supply logic levels common in modern digital interfaces. Consider the 81 pF capacitance value if signal integrity at high frequencies is critical. Compare against alternative TVS diodes only if higher voltage ratings or different package styles are required for the specific application environment.

Part Context

This part belongs to Semtech’s MicroClamp (SurgeSwitch) series, specialized for ESD and transient protection. It complements other variants in the lineup offering different voltage ratings and channel counts. The series targets the growing demand for compact protection solutions in smartphones, tablets, and wearable devices where board real estate is limited.

Replacement Considerations

Direct substitutes include UCLAMP3311ZVTFT for lower voltage applications. Verify pin compatibility and package similarity before swapping. Cross-reference datasheets for clamping voltage and capacitance differences to ensure circuit performance remains unaffected during replacement.
