TPR6040F20-S3TR-S

Overview

The TPR6040F20-S3TR-S is a high-precision shunt voltage reference from the TPR6040 family, manufactured by 3PEAK. It provides a fixed output voltage of 2.048 V with B-grade accuracy (±0.2% tolerance) and a maximum temperature coefficient of 50 ppm/°C over an operating range of −40°C to +125°C. The device operates within a cathode current range of 150 μA to 15 mA and features 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).

Feature Summary

• Guaranteed high initial accuracy and low temperature coefficient across the full industrial temperature range.
• Operates with a wide sink current capability ranging from 150 μA to 15 mA.
• Maintains stability when connected to any capacitive load without oscillation.
• Includes robust electrostatic discharge protection for manufacturing safety.

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm that the B-grade accuracy specifications align with design requirements. Ensure the sourcing channel provides genuine components with traceable documentation. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a fixed 2.048 V reference is required with tight tolerance constraints. The wide operating current range allows flexibility in biasing resistor selection. Consider the thermal performance and package size for space-constrained PCB layouts. Evaluate noise specifications against signal integrity requirements for sensitive analog front ends.

Part Context

This part belongs to the TPR6040 series of high-precision shunt voltage references. The family offers multiple fixed output voltages including 2.5 V, 3 V, 3.3 V, 4.096 V, and 5 V. All variants share similar electrical characteristics and packaging options, differing primarily in their nominal output voltage and corresponding marking codes.

Replacement Considerations

Direct substitutes include other TPR6040 family members such as TPR6040F25-S3TR-S or TPR6040F33-S3TR-S if different voltage levels are acceptable. Cross-brand replacements require verification of pin compatibility, accuracy grades, and thermal coefficients.

FAQ

What is the recommended handling for Pin 3 on the TPR6040?

Pin 3 is designated as NC (No Connect). It must be left floating or connected directly to Pin 2 (Anode/Ground).

Does the TPR6040 require external compensation capacitors?

No, the device is designed to be stable with any capacitive load and does not require external compensation components.
