ZRC400A03STZ

Overview

The ZRC400A03STZ is a precision micropower voltage reference delivering a nominal output of 4.096V using bandgap circuit design. It operates within an industrial temperature range from -40°C to +85°C and requires no external stabilizing capacitor. The device maintains stability with capacitive loads and supports an operating current between 23μA and 5mA, with absolute maximum ratings up to 25mA reverse/forward current and 200mA transient capability. It features a typical temperature coefficient of 30ppm/°C and a slope resistance of 0.4Ω.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring an external stabilizing capacitor
• Capable of withstanding transient effects and currents up to 200mA due to rugged construction
• Achieves stable operating conditions in less than 10 microseconds
• Low knee current allows suitability for low power and battery-powered applications

Applications

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

Procurement Notes

Verify the specific package suffix against official documentation, as the provided datasheet lists E-Line variants (R, A, Y) rather than STZ. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as this information is not explicitly stated in the source material. Ensure the ordering code matches the required tolerance level and pin configuration before procurement.

Selection Notes

Select this component when space-saving through-hole packages are required alongside precise voltage referencing. The device is suitable for designs needing fast transient response and high overload protection. Consider the available tolerance options and package styles to match board layout constraints. Verify that the operating current range aligns with the system's power budget requirements.

Part Context

The ZRC400 series includes various package options such as SOT23, SO8, and E-Line styles. The ZRC400A03 variant specifically denotes a 3% tolerance version in an E-Line package. Other suffixes indicate different tolerances and physical form factors within the same functional family.

Replacement Considerations
