Overview
The LD6816CX4/C25P,315 is a quad-channel electrostatic discharge (ESD) protection device manufactured by Nexperia. It is designed to safeguard high-speed data interfaces against transient voltage events. The component utilizes a compact Wafer-Level Chip-Scale Package (WLCSP) with a 0.4 mm pitch, facilitating integration into space-constrained portable electronics. It provides system-level protection for sensitive receiver and transmitter ports in digital communication systems.
Feature Summary
- Provides comprehensive ESD protection for multiple high-speed interface channels simultaneously
- Features ultra-low line capacitance to maintain signal integrity during high-frequency operation
- Incorporates rail-to-rail clamping diodes to protect downstream components from overvoltage conditions
Applications
- Protection of High-Definition Multimedia Interface (HDMI) ports
- Safeguarding DisplayPort connections in display devices
- Shielding USB and external Serial Advanced Technology Attachment (eSATA) interfaces
- Protection for Low Voltage Differential Signaling (LVDS) lines
Procurement Notes
Verify the specific suffix C25P,315 against official Nexperia documentation to confirm tape and reel specifications. Ensure compatibility with automated surface-mount assembly processes. Confirm that the WLCSP package dimensions align with the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring multi-channel protection for mixed high-speed interfaces within minimal board area constraints. It is suitable for applications demanding low parasitic capacitance to prevent signal degradation. Consider its robust clamping characteristics for environments prone to significant electrostatic discharge events.
Part Context
This device belongs to Nexperia's portfolio of ESD protection solutions aimed at enhancing reliability in consumer electronics. It addresses the growing need for compact, high-performance protection in mobile handsets and portable media players. The product supports design miniaturization while maintaining compliance with international safety standards for electrostatic discharge immunity.
Replacement Considerations
Consult official Nexperia substitution guides for verified equivalent part numbers. Do not assume functional interchangeability with generic ESD arrays without verifying pinout compatibility and electrical parameter alignment.
