TPR6040F33-S3TR

Overview

The TPR6040F33-S3TR is a high-precision shunt voltage reference from 3PEAK, providing a fixed output of 3.3 V with Grade B accuracy (±0.2% tolerance) and a temperature coefficient of 50 ppm/°C. It operates within a 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), stable performance with any capacitive load, and comes in a SOT23G-3 package.

Feature Summary

• Guaranteed high initial accuracy and low temperature coefficient for precise voltage regulation
• Operates with wide cathode current range from 150 μA to 15 mA
• Maintains stability with any capacitive load without oscillation
• Extended operating temperature range from −40°C to +125°C

Applications

• Power supply monitoring and control
• LED lighting systems
• Current sensing circuits
• Precision instrumentation
• Industrial equipment

Procurement Notes

Verify the specific suffix -S3TR corresponds to the tape and reel packaging format required for automated assembly. Confirm that the Grade B specifications meet the design tolerance requirements. Ensure the SOT23G-3 footprint matches the PCB layout. Check RoHS compliance status if halogen-free materials are mandated by project specifications.

Selection Notes

Select this component when a stable 3.3 V reference is needed in space-constrained designs requiring shunt topology. The SOT23G-3 package offers a compact solution compared to larger alternatives. Consider the 150 μA minimum operating current for low-power applications and verify that the 50 ppm/°C drift fits the thermal environment constraints.

Part Context

This part belongs to the TPR6040 family of high-precision shunt voltage references manufactured by 3PEAK. The family includes various fixed output voltages such as 2.048 V, 2.5 V, 3 V, 4.096 V, and 5 V. All variants share similar electrical characteristics and package options, differing primarily in their nominal output voltage and corresponding marking codes.

Replacement Considerations

Direct substitutes include other TPR6040 variants with different output voltages if the system allows voltage adjustment. Cross-brand replacements require matching the 3.3 V output, ±0.2% accuracy, SOT23G-3 package, and operating current range. Verify pinout compatibility and thermal performance before substitution.
