ZRC250F02TA

Overview

The ZRC250F02TA is a precision micropower voltage reference utilizing bandgap circuit design to deliver a fixed 2.5V output. It operates within an industrial temperature range of -40°C to +85°C and requires no external stabilizing capacitor. The device maintains stability with capacitive loads and supports operating currents between 20µA and 5mA, with rugged handling of transients up to 200mA. It features ±2% initial accuracy, a typical temperature coefficient of 30ppm/°C, and low knee current characteristics.

Feature Summary

• Bandgap circuit design provides stable 2.5V reference without requiring external stabilization capacitors
• Capable of withstanding transient effects and high currents up to 200mA due to rugged construction
• Fast transient response achieves stable operating conditions in less than 10 microseconds
• Operates effectively at low currents with a typical knee current of 15µA

Applications

• Battery powered and portable equipment
• Instrumentation systems
• Test equipment

Procurement Notes

Verify the specific tolerance suffix (F02) corresponds to the required ±2% accuracy for your application. Confirm package type matches SOT-23 requirements. Check RoHS compliance status as per latest manufacturer documentation. Ensure supply chain sources are authorized distributors to avoid counterfeit components. Review absolute maximum ratings before integration into final designs.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside precise voltage referencing. Consider the ±2% tolerance if tighter specifications like ±1% are not necessary. Evaluate the 30ppm/°C temperature coefficient against environmental operating ranges. Verify that the 20µA minimum operating current aligns with system power budget constraints.

Part Context

This part belongs to the ZRC250 series from Diodes Incorporated, designed for precision applications. The 'F' suffix indicates the SOT-23 surface mount package, while '02' denotes the ±2% tolerance variant. It serves as a modern replacement for obsolete through-hole E-Line variants within the same family.

Replacement Considerations

ZRC250F01TA offers ±1% tolerance. ZRC250F03TA offers ±3% tolerance. Both utilize the identical SOT-23 package and electrical characteristics except for accuracy.
