HCLAMP5068ZATFT

Overview

The HCLAMP5068ZATFT is a single-line transient voltage suppression (TVS) diode from Semtech's HClamp family, designed for electrostatic discharge (ESD) and electrical overstress (EOS) protection. It features a reverse working voltage of 5V and a typical capacitance of 68pF. The device utilizes an SLP0603P2X3F surface-mount package. It provides robust protection against high-voltage transients while maintaining signal integrity on data lines.

Feature Summary

• Single-line configuration for protecting individual high-speed data interfaces
• Low clamping voltage characteristics to safeguard sensitive downstream components
• Optimized for minimal signal distortion in high-frequency applications

Applications

• Protection of USB Type-C ports
• High-speed serial data line protection
• Mobile device interface circuits

Procurement Notes

Verify component authenticity through authorized Semtech distributors or certified suppliers. Confirm the specific suffix ZATFT matches design requirements. Check RoHS compliance status and ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage prior to assembly.

Selection Notes

Select this component when a single-channel protection solution with moderate capacitance is required. The 68pF value suits applications where extreme low-capacitance is not critical but higher surge handling may be needed compared to lower capacitance variants. Ensure the 5V operating voltage aligns with the protected circuit's nominal levels.

Part Context

This part belongs to Semtech's HClamp series, which focuses on compact ESD protection solutions. It complements other devices like the RClamp and µClamp families, offering specialized protection for consumer electronics and industrial interfaces requiring reliable transient suppression in small form factors.

Replacement Considerations

Consult Semtech documentation for direct pin-compatible alternatives within the HClamp series. Verify that any substitute maintains the same 5V rating and comparable capacitance to ensure signal integrity is preserved without redesigning the PCB layout.
