TS4040DIZ-2.5

Overview

The TS4040DIZ-2.5 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 2.5V output voltage across the industrial temperature range of -40°C to +85°C. It features high precision with ±1% tolerance at 25°C and a maximum temperature coefficient of 150ppm/°C. The device operates with ultra-low current consumption, typically 40µA, and supports a cathode current range from 60µA to 15mA. It is housed in a TO92 plastic package.

Feature Summary

• Provides precise 2.5V reference voltage with ±1% initial accuracy
• Ultra-low power consumption suitable for battery-operated designs
• High stability when used with capacitive loads
• Operates reliably within the industrial temperature range

Applications

• Computers
• Instrumentation
• Battery chargers
• Switch Mode Power Supply
• Battery operated equipments

Procurement Notes

Verify that the specific ordering suffix 'Z' corresponds to the TO92 plastic package configuration as defined in the datasheet. Confirm the 'D' designation indicates the 1% precision variant rather than the standard 2% version. Ensure the component meets RoHS3 compliance requirements if applicable to the project specifications.

Selection Notes

Select this component for applications requiring space-saving through-hole packaging combined with low quiescent current. The TO92 form factor is advantageous where surface-mount options are unsuitable. Consider the 1% tolerance requirement against cost constraints, noting that lower precision alternatives exist within the same family.

Part Context

This part belongs to the TS4040 series of micropower shunt voltage references. The series includes variants with different tolerances (±1% and ±2%) and packages (SOT23-3 and TO92). The TS4040DIZ-2.5 specifically denotes the 1% precision model in the TO92 housing, offering a robust solution for general-purpose voltage referencing.

Replacement Considerations

Standard direct substitutes include other industry-standard shunt references. Verify pinout compatibility and thermal characteristics when replacing. Cross-reference with similar TO92 packaged references ensuring identical 2.5V output and current handling capabilities.
