TPR6040F30-S3TR-S

Overview

The TPR6040F30-S3TR-S is a high-precision shunt voltage reference from the 3PEAK TPR6040 family, providing a fixed output voltage of 3 V. It features B-grade accuracy with a maximum initial tolerance of 0.2% and a temperature coefficient of 50 ppm/°C across an operating range of −40°C to +125°C. The device supports a cathode current range of 150 μA to 15 mA and exhibits a typical dynamic impedance of 0.3 Ω. Packaged in SOT23G-3, it is stable with any capacitive load and includes ESD protection rated at 4000 V (HBM) and 1000 V (CDM).

Feature Summary

• Fixed 3 V output with B-grade precision ensuring tight initial tolerance and low temperature drift.
• Operates reliably within a wide cathode current range from 150 μA to 15 mA.
• Maintains stability when connected to any capacitive load without oscillation risks.
• Provides robust electrostatic discharge protection for manufacturing and handling safety.

Applications

• Power supply monitoring and regulation circuits
• LED lighting driver references
• Precision current sensing interfaces
• Industrial instrumentation signal conditioning

Procurement Notes

Verify the specific suffix 'S3TR' corresponds to the tape and reel packaging format containing 3000 units per reel. Confirm that the 'B' grade designation aligns with the required 0.2% tolerance specification for your design. Ensure the SOT23G-3 package dimensions match your PCB footprint constraints. Check for RoHS compliance and halogen-free status if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a fixed 3 V reference is required with moderate precision (0.2%) and low cost. It is suitable for applications where the cathode current can be maintained between 150 μA and 15 mA. Consider the SOT23G-3 package size for space-constrained designs. If tighter accuracy (0.1%) or lower noise is needed, evaluate the A-grade variants or other series within the manufacturer's portfolio.

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, 2.5 V, 3.3 V, 4.096 V, and 5 V. All variants share similar electrical characteristics regarding temperature stability and dynamic impedance, differing primarily in their nominal output voltage and associated grading options.

Replacement Considerations

Direct substitutes within the same family include TPR6040F25-S3TR-S (2.5 V), TPR6040F33-S3TR-S (3.3 V), TPR6040F40-S3TR-S (4.096 V), and TPR6040F50-S3TR-S (5 V). These parts share identical pinouts, packages, and thermal characteristics, allowing for potential voltage adjustment via external resistor networks if the system architecture permits.
