ZXRE125FN8TA

Overview

The ZXRE125FN8TA is a bandgap voltage reference IC providing a fixed 1.22V output with ±3% initial accuracy. It operates within a current range of 4µA to 20mA and features a typical temperature coefficient of 75ppm/°C. The device is housed in an SOT-23 surface-mount package, measuring 3.04mm by 2.10mm. It functions reliably between -40°C and +85°C, offering unconditionally stable performance suitable for precision applications.

Feature Summary

• Provides a precise 1.22V micropower reference voltage
• Operates stably across a wide current range from 4µA to 20mA
• Designed for high tolerance against capacitive loads

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'FN8TA' against official Diodes Incorporated documentation to confirm availability status and exact tolerance grade. Confirm that the ordering information matches the required 3% tolerance specification. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement plans.

Selection Notes

Select this component when a compact SOT-23 footprint is required alongside a 1.22V reference. The 3% tolerance variant is appropriate for general-purpose applications where extreme precision is not critical. Consider the 75ppm/°C temperature coefficient for environments with moderate thermal variations.

Part Context

This part belongs to the ZXRE125 series, which offers various tolerance grades including 0.5%, 1%, 2%, and 3%. The series provides pin-compatible replacements for older ZRA124 and ZRA125 references. The FN8TA designation indicates the specific packaging and tolerance configuration within this family.

Replacement Considerations

The datasheet identifies the ZXRE125 as a pin-for-pin compatible replacement for the ZRA124 and ZRA125 series. Verify electrical parameters such as knee current and temperature coefficient when substituting these legacy components.
