TPSF12C3QDYYRQ1

Overview

The TPSF12C3QDYYRQ1 is an automotive-grade active EMI filter designed for three-phase systems. Manufactured by Texas Instruments, this component operates within a supply voltage range of 12 V and functions reliably across an extended temperature range from -40°C to +150°C. It is housed in a compact 14-SOT-23-THIN package, suitable for surface-mount installation. The device integrates active filtering capabilities to mitigate electromagnetic interference in demanding automotive environments.

Feature Summary

• Provides active common-mode filtering specifically engineered for three-phase power systems in automotive applications.
• Operates with a single 12 V supply voltage, simplifying integration into existing vehicle electrical architectures.
• Engineered for high-temperature reliability, supporting operation up to +150°C for robust performance in harsh under-hood conditions.

Applications

• Active EMI suppression in automotive three-phase motor drive systems
• Electromagnetic interference mitigation in electric vehicle powertrains
• Common-mode noise reduction in industrial automotive control units

Procurement Notes

Verify the complete part number including the Q1 automotive qualification suffix and DYYRQ1 tape-and-reel packaging code against official Texas Instruments documentation. Confirm that the specific ordering suffix matches the required reel quantity and package variant. Ensure compatibility with the target three-phase system voltage levels and thermal management requirements before procurement.

Selection Notes

Select this component when designing automotive systems requiring active common-mode EMI filtering for three-phase configurations. Consider the 12 V operating voltage and the extended +150°C maximum junction temperature capability. Evaluate the 14-SOT-23-THIN package size constraints against the available PCB real estate. Verify that the active filtering topology aligns with the specific noise spectrum and attenuation requirements of the application.

Part Context

This part belongs to the TPSF12C series of automotive active filters from Texas Instruments. It is distinct from passive EMI filters or other logic families like the SN74HCS or TLC69623 listed in general catalogs. The Q1 designation indicates compliance with automotive quality standards, differentiating it from standard commercial grade components.
