ZRC250N803TA

Overview

The ZRC250N803TA is a precision micropower voltage reference providing a fixed 2.5V output, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and operates within an industrial temperature range of -40°C to +85°C. The device features a typical temperature coefficient of 30ppm/°C and maintains stability without requiring an external stabilizing capacitor. It supports recommended operating currents between 20μA and 5mA, with absolute maximum ratings allowing for transient handling up to 200mA.

Feature Summary

• Bandgap circuit design ensures stable voltage reference without the need for external capacitors
• Capable of withstanding transient effects and high currents due to rugged 20-volt processing
• Fast switching capability allows the device to reach stable operating conditions in microseconds

Applications

• Battery powered and portable equipment
• Instrumentation systems
• Test equipment

Procurement Notes

Verify the specific suffix N8 corresponds to the SO-8 package configuration before procurement. Confirm that the 1% tolerance variant aligns with system accuracy requirements. Ensure the component meets RoHS3 compliance standards if required by the manufacturing process. Cross-reference the datasheet revision date to confirm electrical characteristics match current production batches.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside low power consumption needs. The wide operating current range suits applications where load conditions vary significantly. Consider the 30ppm/°C temperature coefficient for environments with moderate thermal fluctuations. Verify that the 2.5V output level matches the reference input requirements of downstream analog-to-digital converters or comparators.

Part Context

This part belongs to the ZRC250 series of precision voltage references from Diodes Incorporated. The series offers multiple package options including SOT23, SO8, and TO-92 styles to accommodate various board layout constraints. The N8 suffix specifically denotes the small outline eight-lead package variant, distinguishing it from the smaller three-terminal surface mount versions.

Replacement Considerations

Direct substitutes include other ZRC250 variants such as ZRC250F01TA (SOT23) or ZRC250N801TA (SO8) if tolerance or package differences are acceptable. Verify pinout compatibility when replacing with different package suffixes within the same family.
