ZR40401F25TA

Overview

The ZR40401F25TA is a precision micropower shunt voltage reference providing a nominal output of 2.5V with an initial accuracy of 1%. Manufactured by Diodes Incorporated, it utilizes a bandgap circuit design and is housed in a surface-mount SOT-23 package. The device operates within a recommended current range of 60µA to 15mA and maintains stability without requiring an external stabilizing capacitor. It features a typical temperature coefficient of 30ppm/°C and achieves stable operating conditions in less than 10µs during transient events.

Feature Summary

• Bandgap circuit design ensures precision voltage regulation without the need for external stabilizing capacitors.
• Capable of reaching stable operating conditions in under 10 microseconds due to superior switching capability.
• Robust construction allows withstand of transient effects and currents up to 200mA despite a maximum rating of 25mA.

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation
• Test equipment
• Data acquisition systems

Procurement Notes

Verify component authenticity through authorized channels as counterfeit electronic components exist. Confirm that the specific ordering suffix matches the required tolerance and package type. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure storage and handling procedures comply with moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this component when a compact surface-mount solution is required for low-power applications. The 1% tolerance variant suits circuits needing higher precision compared to standard 2% options. Consider the SOT-23 package constraints regarding thermal dissipation and physical space. Evaluate if the micropower characteristics align with the system's battery life requirements.

Part Context

This part belongs to the ZR4040 series of precision voltage references produced by Diodes Incorporated. The series includes variants with different tolerances (0.5%, 1%, 2%) and packages (SOT-23, E-Line). The F suffix specifically denotes the SOT-23 surface-mount package configuration.

Replacement Considerations

Compatible substitutes include other parts from the ZR4040 family such as ZR40402F25TA or ZR404005F25TA, which share the same pinout and core functionality but offer different tolerance levels. Verify electrical parameters against original requirements when selecting alternatives.
