VEMI255A-HS3-GS08

Overview

The VEMI255A-HS3-GS08 is a second-order low-pass RC (Pi) EMI filter designed for surface mount applications. It features two channels with a resistance of 50 ohms and capacitance of 37pF per channel. The device has a cutoff frequency of 100MHz and supports a current rating of 4A. Packaged in a compact 6-WDFN裸焊盘 (LLP75) footprint measuring 1.60mm x 1.60mm, it operates within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates dual-channel RC Pi-filter topology for effective common-mode noise suppression
• Provides integrated ESD protection capabilities alongside signal filtering
• Utilizes a compact 1.60mm x 1.60mm WDFN package for space-constrained designs

Applications

• Mobile device data line protection
• High-speed interface signal conditioning
• Portable electronics EMI mitigation

Procurement Notes

Verify component authenticity through authorized distributors as the part is discontinued. Confirm RoHS3 compliance and MSL Level 1 status during sourcing. Check for valid replacement options such as updated Vishay series components if long-term supply stability is required for production.

Selection Notes

Select this component when designing circuits requiring combined EMI filtering and ESD protection for high-speed data lines. Ensure the 50-ohm impedance matches the transmission line requirements. Verify that the 4A current rating exceeds the maximum operational load of the target application.

Part Context

This component belongs to the VEMI25 series from Vishay General Semiconductor - Diodes Division. It is specifically engineered for protecting sensitive electronic interfaces against electromagnetic interference and electrostatic discharge events in portable consumer devices.

Replacement Considerations

The VEMI255A-HS3-GS08 is marked as obsolete. Direct substitutes are not explicitly listed in the provided documentation; verify equivalent RC Pi-filter configurations from current Vishay portfolios or compatible third-party manufacturers.
