ZR40401F50TC

Overview

The ZR40401F50TC is a precision micropower shunt voltage reference from Diodes Incorporated, delivering a nominal output of 5.0 V with an initial accuracy of 1%. It utilizes a bandgap circuit design and operates within a recommended current range of 60 µA to 15 mA. The device features a typical temperature coefficient of 20 ppm/°C and maintains stability without requiring an external stabilizing capacitor. It supports operation across a wide temperature range of -55°C to +125°C.

Feature Summary

• Bandgap circuit design provides stable voltage output without the need for external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20V 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 the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'F' (SOT-23) and 'R' (E-Line) packages. Confirm RoHS compliance status and lead times directly with Diodes Incorporated or authorized distributors, as availability may vary based on production cycles.

Selection Notes

Select this component when high precision (1% tolerance) and low power consumption are required in space-constrained designs. Ensure the application current remains between 60 µA and 15 mA for optimal performance. Consider the SOT-23 package if surface-mount technology is preferred over through-hole alternatives.

Part Context

This part belongs to the ZR4040-5.0 series of precision voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerances (1% and 2%) and package options (SOT-23 and E-Line). It is designed for applications demanding stable reference voltages in compact electronic systems.

Replacement Considerations

ZR40402F50TA: Offers similar functionality with 2% tolerance instead of 1%, maintaining the same SOT-23 package and electrical characteristics.
