ZXRE1004ERSTZ

Overview

The ZXRE1004ERSTZ is a discontinued shunt precision voltage reference from Diodes Incorporated, featuring a fixed output of 1.22V with a ±2% initial accuracy tolerance. It operates within an 8µA to 20mA current range and exhibits a typical temperature coefficient of 20ppm/°C. The device utilizes an E-Line (TO-92 style) package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides a stable 1.22V bandgap reference suitable for low-power applications
• Offers high capacitive load tolerance ensuring unconditional stability
• Features ultra-low knee current operation for battery-powered efficiency

Applications

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

Procurement Notes

This component is officially obsolete and not recommended for new designs. Verify end-of-life status before procurement. Contact the manufacturer or authorized distributors for final purchase options or transition planning. Ensure compliance with RoHS and lead-free requirements as specified in the datasheet.

Selection Notes

Select this part only if legacy compatibility with REF1004, LT1004, or LM185/385 series is required. Consider tighter tolerance variants like ZXRE1004DFTA for 1% accuracy. Evaluate space constraints as the E-Line package is larger than SOT23 alternatives.

Part Context

Part of the ZXRE1004 family offering pin-for-pin compatibility with industry-standard references. Designed for micro-power applications requiring precise voltage regulation in portable devices. The E-Line variant provides through-hole mounting options.

Replacement Considerations

Officially recommended replacement: ZXRE125. Verify functional equivalence and pinout compatibility before substitution.
