ZR404005F25TC

Overview

The ZR404005F25TC is a precision micropower voltage reference providing a nominal output of 2.5 volts, 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 60 µA to 15 mA and maintains excellent performance up to an absolute maximum of 25 mA. It features a typical temperature coefficient of 30 ppm/°C and a slope resistance of 0.4 Ω. The component is housed in a small outline SOT23 package (suffix F) with a tolerance of 0.5%. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200 mA due to rugged 20-volt processing.
• Superior switching capability 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 that the ordering suffix 'F' corresponds specifically to the SOT23 surface mount package configuration. Confirm the '05' designation indicates the required 0.5% tolerance level for your application. Ensure the manufacturer is identified as Diodes Incorporated to match the specified datasheet parameters. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when space-saving is critical due to its compact SOT23 package form factor. It is suitable for low-power applications given the minimum operating current of 60 µA. Choose this specific variant if a 0.5% voltage tolerance is required rather than the standard 1% or 2% options. Ensure the system can accommodate the recommended operating current range of 60 µA to 15 mA for optimal performance.
