ZR40402F25TC

Overview

The ZR40402F25TC is a precision micropower voltage reference providing a nominal output of 2.5 volts, 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 60 µA to 15 mA, with absolute maximum ratings allowing for transient currents up to 200 mA. Key electrical specifications include a typical temperature coefficient of 30 ppm/°C, a slope resistance of 0.4 Ω, and a wideband noise voltage of 45 µVrms. Initial accuracy is specified at ±2%, and the component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage regulation without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and high currents up to 200 mA due to rugged construction.
• Fast transient response allows the device to reach stable operating conditions in less than 10 microseconds.

Applications

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

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'F' for SOT-23 packaging. Confirm RoHS compliance status and lead times directly with Diodes Incorporated or authorized distributors, as availability may vary. Ensure the procurement channel provides valid traceability for this electronic component.

Selection Notes

Select this component when space-saving surface-mount integration is required alongside low power consumption. The 2.5-volt output and ±2% tolerance suit applications needing precise references without complex calibration. Consider the 60 µA minimum operating current requirement to ensure proper regulation during low-load conditions.
