ZRC400A01STZ

Overview

The ZRC400A01STZ is a precision micropower voltage reference providing a fixed output of 4.096 V based on bandgap circuit design. It operates within a recommended current range of 23 μA to 5 mA and supports an absolute maximum reverse current of 25 mA. The device features a typical temperature coefficient of 30 ppm/°C and maintains stability without external capacitors, even with capacitive loads. Initial accuracy is specified at ±1%. It withstands transient effects up to 200 mA and reaches stable operating conditions in less than 10 μs.

Feature Summary

• Bandgap circuit design ensures stable voltage output without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200 mA due to rugged 20 volt processing.
• Provides superior switching capability with stable operating conditions reached in under 10 microseconds.

Applications

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

Procurement Notes

Verify the specific package suffix against official documentation, as the STZ designation requires confirmation of the exact physical housing type (e.g., E-Line or SOT-23) and pin configuration. Confirm that the ±1% tolerance variant matches the required application precision. Ensure the operating environment remains within the -40°C to +85°C industrial temperature range for guaranteed performance specifications.

Selection Notes

Select this component when space-saving surface mount or through-hole packages are required alongside high precision. The low knee current makes it suitable for battery-powered applications where quiescent current must be minimized. Consider the ±1% initial accuracy and low temperature coefficient for metering systems requiring high measurement reliability over varying thermal conditions.

Part Context

This part belongs to the ZRC400 series of precision voltage references manufactured by Diodes Incorporated. The series offers multiple tolerance options and package styles, including SOT-23, SO8, and E-Line configurations. The ZRC400A01STZ specifically denotes the 1% tolerance version housed in a specific leaded package format designed for general-purpose precision reference applications.
