ZRC400A02STZ

Overview

The ZRC400A02STZ is a precision micropower voltage reference providing a nominal output of 4.096V, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to achieve high stability without requiring an external stabilizing capacitor. The device operates within a recommended current range of 23μA to 5mA and supports an absolute maximum reverse current of 25mA. It features a typical temperature coefficient of 30ppm/°C and maintains stability with capacitive loads. The component is housed in an E-Line package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external stabilization capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20-volt processing.
• Provides superior switching capability, reaching stable operating conditions in less than 10 microseconds.

Applications

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

Procurement Notes

Verify the specific package suffix against the manufacturer's ordering information to ensure correct pin configuration. Confirm that the required tolerance matches the 'A' designation for ±2% accuracy. Check datasheet limits for operating current and temperature range to ensure compatibility with the target application environment before finalizing procurement.

Selection Notes

Select this component when space-saving through-hole or standard packages are preferred over surface-mount options. It is suitable for low-power applications requiring operation down to 23μA. Consider the ±2% initial accuracy and 30ppm/°C temperature coefficient for precision requirements. Ensure the load does not exceed the recommended operating current of 5mA for optimal performance.
