VEMI85AA-HGK-GS08

Overview

The VEMI85AA-HGK-GS08 is an eight-channel RC Pi EMI filter manufactured by Vishay General Semiconductor - Diodes Division. It features a second-order low-pass configuration with integrated ESD protection, housed in a 16-UFDFN Exposed Pad surface-mount package. The component provides a resistance of 100 Ohms and capacitance of 36 pF per channel, supporting a maximum current of 4 A. Designed for high-density applications, it operates within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates eight independent channels for simultaneous signal filtering
• Combines EMI suppression with electrostatic discharge (ESD) protection capabilities
• Utilizes a compact UFDFN exposed pad package for space-constrained designs

Applications

• High-speed data line protection in portable electronics
• EMI filtering for USB and HDMI interfaces
• Signal conditioning in automotive infotainment systems

Procurement Notes

Verify the specific suffix GS08 against the manufacturer's latest documentation to confirm RoHS compliance status and lead-free characteristics. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when multiple differential or single-ended lines require combined EMI attenuation and ESD safeguarding in a minimal footprint. The 100 Ohm resistance and 36 pF capacitance values are suitable for standard high-speed digital interfaces. Consider the 4 A current rating and thermal performance of the exposed pad for power dissipation requirements in dense assemblies.

Part Context

This device belongs to Vishay's family of multi-channel EMI filters designed for modern electronic systems requiring robust signal integrity. It addresses the increasing need for compact protection solutions in consumer and industrial devices where board space is limited. The integration of filtering and ESD functions reduces the component count compared to discrete solutions.
