ZRA245F01TA

Overview

The ZRA245F01TA is a precision shunt voltage reference from Diodes Incorporated, providing a fixed output of 2.45 V with an initial accuracy of ±1%. It utilizes a bandgap circuit design and operates within a recommended current range of 2 mA to 120 mA. The device features a typical temperature coefficient of 15 ppm/°C and a slope resistance of 0.26 Ω. It is housed in the SOT-23 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design for stable voltage reference without external stabilizing capacitors
• Capacitive load stability for simplified circuit implementation
• Small outline SOT-23 package suitable for space-constrained applications

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation
• Test equipment
• Data acquisition systems

Procurement Notes

Verify the specific suffix F01 against official datasheets to confirm the SOT-23 package and ±1% tolerance. Ensure compatibility with the required operating current range of 2 mA to 120 mA for your application. Confirm that the industrial temperature rating meets environmental requirements.

Selection Notes

Select this component when a precise 2.45 V reference is needed in a compact SOT-23 footprint. It is suitable for designs requiring high accuracy (±1%) and low temperature drift (15 ppm/°C). Consider the maximum operating current of 120 mA for power budget calculations.

Part Context

This part belongs to the ZRA245 series of precision voltage references manufactured by Diodes Incorporated. The series offers various tolerances and packages, including SOT-23, SO8, and TO-92 styles. The ZRA245F01TA specifically denotes the SOT-23 package variant with 1% accuracy.

Replacement Considerations

Check for other ZRA245 variants with different tolerances or packages if availability is an issue. Verify pinout compatibility for direct replacement in existing SOT-23 footprints.
