ZRC400F03TC

Overview

The ZRC400F03TC is a precision micropower voltage reference providing a nominal output of 4.096 V, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and is housed in an SOT-23 surface-mount package. The device operates within a recommended current range of 23 μA to 5 mA, with a typical knee current of 18 μA. It features a 1% initial accuracy tolerance and maintains stability without requiring external capacitors. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design for stable micropower operation
• Capacitor-free stability with capacitive loads
• Low knee current for battery-powered applications
• Rugged design withstands transient currents up to 200 mA

Applications

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

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'TA' for tape-and-reel packaging. Confirm availability status, as some variants are marked obsolete. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications (PCN) regarding manufacturing sites or materials before finalizing procurement.

Selection Notes

Select this component when space-saving SOT-23 packaging is required alongside high precision. The low operating current makes it suitable for energy-constrained designs. Verify that the 1% tolerance meets system requirements. Consider the 20V processing capability if the application involves significant transient voltage events.

Part Context

This part belongs to the ZRC400 series of precision voltage references. The series includes various tolerance options and package types, such as E-Line through-hole packages which are noted as obsolete. The ZRC400F03TC represents the 3% tolerance variant in a small outline surface mount form factor.

Replacement Considerations

Check for direct replacements within the ZRC400 family, such as ZRC400F01TA for tighter tolerances. Note that E-Line variants are obsolete; SOT-23 versions are the recommended alternatives.
