TPR6040F25-S3TR

Overview

The TPR6040F25-S3TR is a high-precision shunt voltage reference from 3PEAK, providing a fixed output of 2.5 V with B-grade accuracy of ±0.2% and a temperature coefficient of 50 ppm/°C. It operates within a cathode current range of 150 μA to 15 mA and supports an extended temperature range of −40°C to +125°C. The device features low dynamic impedance (0.8 Ω max) and stable performance with any capacitive load. Packaged in SOT23G-3, it includes ESD protection rated at 4000 V HBM and 1000 V CDM.

Feature Summary

• Guaranteed high initial accuracy and low temperature coefficient across the full operating range
• Operates stably with any capacitive load without oscillation risks
• Extended thermal stability covering industrial and automotive environments
• Integrated electrostatic discharge protection for enhanced reliability

Applications

• Power supply monitoring and regulation
• LED lighting control circuits
• Precision current sensing systems
• Industrial instrumentation and data acquisition

Procurement Notes

Verify the specific suffix 'S3TR' corresponds to the tape and reel packaging format containing 3000 units per reel. Confirm the marking code 'R6C' matches the required traceability standards. Ensure the RoHS compliant and halogen-free status meets environmental regulations for the target assembly process. Validate that the MSL level 3 rating aligns with the facility's floor life requirements.

Selection Notes

Select this component when a fixed 2.5 V reference is required with tight tolerance specifications. The B-grade accuracy suits applications needing better than 0.5% precision without the cost of A-grade parts. The wide operating current range allows flexibility in biasing resistor selection. Consider the SOT23G-3 package size for space-constrained PCB layouts requiring surface-mount integration.

Part Context

This part belongs to the TPR6040 family of high-precision shunt voltage references manufactured by 3PEAK. The family offers multiple fixed output voltages including 2.048 V, 3 V, 3.3 V, 4.096 V, and 5 V. All variants share identical pinouts, packages, and general electrical characteristics, differing primarily in their nominal output voltage and corresponding temperature coefficients.

Replacement Considerations

Direct substitutes within the same family include TPR6040F20-S3TR, TPR6040F30-S3TR, TPR6040F33-S3TR, TPR6040F40-S3TR, and TPR6040F50-S3TR. These parts maintain identical pin configurations and package dimensions but provide different fixed output voltages. Verify that the system design can accommodate the alternative voltage levels before substitution.
