ZR2431G02TA

Overview

The ZR2431G02TA is an adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides a programmable output voltage ranging from 1.25 V to 15 V, set via external resistors. The device features a TO-92 through-hole package and offers initial accuracy of 2.5%. It operates with a current sink capability between 100 µA and 25 mA, maintaining stability over a temperature range of -40°C to +85°C with a maximum temperature coefficient of 52 ppm/°C.

Feature Summary

• Adjustable output voltage programmable between 1.25 V and 15 V using two external divider resistors
• Temperature compensated for stable operation across the full industrial temperature range
• High output current handling capability supporting up to 25 mA sink current
• Low output noise characteristics suitable for precision reference applications

Applications

• Precision voltage references in measurement equipment
• Programmable power supply regulation circuits
• Industrial control system monitoring
• Battery management systems requiring stable reference voltages

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified agents. Confirm package integrity and pin alignment for TO-92 installation. Ensure environmental compliance documentation matches project requirements. Cross-reference datasheet revisions to confirm parameter consistency. Validate supplier authorization status before procurement to avoid counterfeit components.

Selection Notes

Select this component when an adjustable shunt regulator with through-hole mounting is required. Consider the 2.5% initial accuracy and 52 ppm/°C temperature coefficient for circuit tolerance analysis. Evaluate the 100 µA minimum operating current against load conditions. Compare against fixed-voltage alternatives if programmability is not needed. Assess thermal performance within the specified -40°C to +85°C operational window.

Part Context

The ZR2431 series represents a family of three-terminal adjustable shunt regulators designed for high-precision applications. This specific variant utilizes a TO-92 package, distinguishing it from surface-mount options like SOT-23 or SOT-223 found in other series members. It serves as a cost-effective solution for voltage referencing where board space allows for through-hole technology.

Replacement Considerations

ZR2431G02 is a compatible alternative within the same product family offering identical electrical specifications and functionality.
