UCLAMP0761ZVTFT

Overview

The UCLAMP0761ZVTFT is a unidirectional transient voltage suppression diode from Semtech’s UCLAMP series, designed for ESD and surge protection. It features a 7.6V working voltage and operates within a -55°C to +85°C temperature range. Housed in a compact 0402 (1006 metric) SMD package, it delivers a peak pulse current of 30A with a capacitance of 400pF. The device withstands 30kV ESD contact and air gap discharge, providing reliable circuit safeguarding.

Feature Summary

• Provides robust electrostatic discharge and transient voltage suppression for sensitive electronic circuits.
• Utilizes a compact surface-mount footprint suitable for space-constrained high-density designs.
• Ensures signal integrity through low capacitance characteristics during normal operation.

Applications

• Protection of portable consumer electronics interfaces
• Surge suppression for automotive data lines
• ESD shielding for industrial communication ports

Procurement Notes

Verify the specific suffix ZVTFT against official Semtech documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SMT assembly processes for the 0402 package. Cross-reference RoHS compliance status directly with the manufacturer's latest certification records prior to final procurement authorization.

Selection Notes

Select this component when unidirectional protection is required for single-ended signal lines operating near 7.6V. The 0402 package offers a balance between power handling and board space efficiency. Evaluate the 400pF capacitance against high-speed interface requirements to ensure minimal signal distortion while maintaining adequate clamping performance for the target application environment.
