ZR40402F25TA

Overview

The ZR40402F25TA is a precision micropower shunt voltage reference providing a nominal output of 2.5V with an initial accuracy tolerance of ±2%. It utilizes a bandgap circuit design and operates within a recommended current range of 60µA to 15mA, though it withstands absolute maximum reverse currents up to 25mA. The device features a typical temperature coefficient of 30ppm/°C and a slope resistance of 0.4Ω. It is housed in a small outline SOT-23 package (suffix F) and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilizing capacitors
• Capable of reaching stable operating conditions in less than 10 microseconds
• Rugged construction allows handling of transient effects and high currents up to 200mA

Applications

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

Procurement Notes

Verify the specific suffix 'F' confirms the SOT-23 surface mount package configuration. Confirm the '2' designation aligns with the required ±2% initial accuracy tolerance for your application. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Check for any specific environmental or export classification codes relevant to your region.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside precise 2.5V referencing. It is suitable for low-power designs due to its minimum operating current of 60µA. Consider the ±2% tolerance and 30ppm/°C drift characteristics against system accuracy needs. Verify that the SOT-23 footprint fits the PCB layout constraints.
