ZR40402F50TA

Overview

The ZR40402F50TA is a precision micropower voltage reference providing a nominal output of 5.0V with an initial tolerance of ±2%. It utilizes a bandgap circuit design and operates within a recommended current range of 60µA to 15mA, making it suitable for low-power applications. The device is housed in a small outline SOT-23 package (suffix F) and supports an operating temperature range from -55°C to +125°C. It features a typical temperature coefficient of 20ppm/°C and maintains stability without requiring an external stabilizing capacitor.

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 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 component authenticity by checking the marking code '50L' on the SOT-23 package against official Diodes Incorporated specifications. Confirm that the ordering suffix 'F' corresponds to the SOT-23 package variant. Ensure compliance with RoHS directives as indicated in manufacturer documentation. Validate the specific ±2% tolerance grade required for the application before procurement.

Selection Notes

Select this component when a fixed 5.0V reference is needed in space-constrained designs utilizing the SOT-23 footprint. It is appropriate for applications requiring operation across the full automotive temperature range (-55°C to +125°C). Consider the ±2% tolerance if higher precision grades like the 1% variant are not strictly necessary for the system accuracy requirements.

Part Context

This part belongs to the ZR4040 series of precision voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerances (1% and 2%) and packages (SOT-23 and E-Line TO-92). The ZR40402F50TA specifically denotes the 2% tolerance version in the surface-mount SOT-23 configuration.

Replacement Considerations

Public confirmed substitute: ZR40401F50TA (1% tolerance variant in same SOT-23 package).
