ZRC250F01TA

Overview

The ZRC250F01TA 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 recommended operating currents between 20 μA and 5 mA. It features ±1% initial accuracy, a typical temperature coefficient of 30 ppm/°C, and wideband noise of 60 μVrms from 10Hz to 10kHz.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilization capacitors
• Capable of withstanding transient effects and high currents up to 200mA due to rugged construction
• Rapid recovery to stable operating conditions in less than 10 microseconds following transients
• Operates effectively across a broad current range from 20 μA to 5 mA for low power applications

Applications

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

Procurement Notes

Verify the specific suffix 'F01' confirms the SOT-23 package and ±1% tolerance level required for your design. Confirm RoHS3 compliance status if mandated by your manufacturing standards. Ensure the ordering quantity aligns with standard reel sizes when sourcing bulk components. Cross-reference the manufacturer part number against authorized distributors to prevent counterfeit procurement.

Selection Notes

Select this component when space constraints necessitate a small outline surface mount package like SOT-23. Choose this variant over higher tolerance options only if ±1% accuracy meets system requirements. Consider the low knee current specification for designs where quiescent power consumption must be minimized. Verify that the maximum reverse current rating of 25 mA fits within the protection limits of your circuit topology.

Part Context

This component belongs to the ZRC250 series of precision voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerance levels and package types, such as the E-Line through-hole packages which are now obsolete. The F01 suffix specifically denotes the SOT-23 surface mount package with ±1% accuracy.

Replacement Considerations

The datasheet notes that all ZRC250A variants (E-Line) are obsolete. The closest alternative for those legacy through-hole requirements is the SOT-23 package version.
