ZXRE125CFTC

Overview

The ZXRE125CFTC is a micropower bandgap voltage reference IC providing a fixed 1.22V output with ±0.5% initial accuracy. It operates within an input current range of 4µA to 20mA and features a typical temperature coefficient of 20ppm/°C. The device is housed in a surface-mount SOT-23 package, measuring 3.04mm by 2.10mm with a maximum height of 1.12mm. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-performance precision voltage reference
• Unconditionally stable under capacitive loads
• Designed for space-constrained applications

Applications

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

Procurement Notes

Verify the specific suffix 'CFTC' against official Diodes Incorporated documentation, as standard datasheets list 'CFTA'. Confirm availability status, as E-line variants are obsolete. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notifications affecting manufacturing sources or materials.

Selection Notes

Select this component when a compact SOT-23 footprint is required alongside tight ±0.5% tolerance. It serves as a pin-compatible replacement for older ZRA124 and ZRA125 series references. Consider the low knee current for battery-powered designs requiring minimal quiescent drain.

Part Context

Part of the ZXRE125 family of micropower voltage references. The C suffix denotes the 0.5% tolerance grade. Other grades include D (1%), E (2%), and F (3%). All variants share identical electrical characteristics and package dimensions, differing only in initial accuracy.

Replacement Considerations

Pin-for-pin compatible with ZRA124 and ZRA125 series voltage references.
