ZXRE1004CFTA

Overview

The ZXRE1004CFTA is a 1.22V bandgap shunt voltage reference in an SOT-23 package, manufactured by Diodes Incorporated. It offers a tight initial accuracy of 0.5% and operates within a recommended current range of 8µA to 20mA. The device features a typical temperature coefficient of 20ppm/°C and maintains stability under capacitive loads. Designed for ultra-low power consumption with a knee current as low as 4µA, it supports operation from -40°C to +85°C.

Feature Summary

Provides high precision with 0.5% tolerance for critical measurement applications
Enables extended battery life through ultra-low operating current consumption
Ensures circuit stability without oscillation when driving capacitive loads
Offers a compact surface-mount footprint suitable for space-constrained designs

Applications

Battery powered equipment
Precision power supplies
Portable instrumentations
Data acquisition systems
A/D and D/A converters

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm final assembly markings match the datasheet specifications. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Validate that the specific lot meets RoHS compliance requirements for intended markets.

Selection Notes

Select this variant specifically for its 0.5% accuracy grade compared to standard tolerances. Evaluate the SOT-23 package dimensions against available board real estate constraints. Consider the minimum operating current requirement relative to the system's quiescent load. Assess thermal management needs based on the specified power dissipation limits.

Part Context

This component belongs to the ZXRE1004 series of micro-power voltage references. It serves as a direct pin-for-pin replacement for legacy REF1004, LT1004, and LM185/385 devices. The series provides a modern alternative to older technologies while maintaining compatibility with existing circuit layouts.
