TDS2261P.C

Overview

The TDS2261P.C is a SurgeSwitch transient voltage suppression device designed for high-speed data line protection. It features an integrated field-effect transistor (FET) that diverts surge energy to ground rather than dissipating it, ensuring stable clamping voltage across varying temperatures and pulse currents. The component provides robust electrostatic discharge (ESD) and electrical overstress (EOS) protection with low capacitance characteristics suitable for signal integrity preservation.

Feature Summary

• Utilizes a precision trigger circuit to activate an FET switch for direct energy diversion to ground
• Maintains constant clamping voltage independent of pulse current magnitude and temperature variations
• Offers superior linear response and lower clamping voltage compared to traditional TVS diodes

Applications

• USB PD VBUS interface protection
• IO-Link interface safeguarding
• Industrial sensor ESD/EOS protection
• PLC I/O module transient suppression
• PoE input protection

Procurement Notes

Verify the specific suffix 'C' against Semtech official documentation to confirm package type or tape/reel specifications. Ensure compatibility with IEC 61000-4-5 standards for industrial environments. Confirm lead-free and RoHS compliance status through manufacturer datasheets prior to procurement.

Selection Notes

Select this component when deterministic EOS protection is required for sensitive interfaces. It is ideal for applications demanding lower clamping voltages than standard TVS devices can provide. Consider its small footprint for space-constrained PCB layouts where high reliability under repeated surge events is critical.

Part Context

Part of Semtech's SurgeSwitch product line, which focuses on protecting interfaces from ESD and EOS events. This series complements other protection solutions like RClamp TVS diodes by offering active switching capabilities for higher performance in harsh electrical environments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Standard TVS diodes may serve as functional alternatives but will not replicate the active energy diversion and constant clamping voltage characteristics of the SurgeSwitch technology.
