ZXRE125FRSTZ

Overview

The ZXRE125FRSTZ is a fixed shunt precision voltage reference IC manufactured by Diodes Incorporated. It provides a stable reference voltage of 1.22V with an initial accuracy of ±3%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 20 mA. It utilizes a TO-92-3 package, suitable for through-hole mounting applications requiring compact form factors.

Feature Summary

• Provides a fixed 1.22V reference output
• Utilizes TO-92-3 through-hole packaging
• Operates across extended industrial temperatures

Applications

• Portable battery-powered equipment
• Temperature measurement systems
• Handheld meters

Procurement Notes

Verify the specific suffix FRSTZ confirms the TO-92-3 package and ±3% tolerance variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required lead time and manufacturing site specifications provided by Diodes Incorporated.

Selection Notes

Select this component when a low-cost, through-hole voltage reference is required for portable or handheld applications. The TO-92-3 package facilitates easy prototyping and assembly on standard PCBs. Consider the ±3% initial accuracy and 75 ppm/°C temperature coefficient for circuit design margins.

Part Context

This component belongs to the ZXRE125 series of shunt voltage references from Diodes Incorporated. The series offers various accuracy grades and packages, including SOT-23 and TO-92 options. The ZXRE125FRSTZ specifically targets cost-sensitive applications where through-hole mounting is preferred over surface mount technology.

Replacement Considerations

Direct substitutes include other ZXRE125 variants with different tolerances or packages, such as ZXRE125EFTA (SOT-23, ±0.5%). Verify pinout compatibility and thermal characteristics when replacing with surface-mount equivalents.
