ZRA245N801TA

Overview

The ZRA245N801TA is a precision two-terminal voltage reference providing a nominal output of 2.45V, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to achieve high stability without requiring an external stabilizing capacitor. The device operates within a recommended current range of 2mA to 120mA and features a typical temperature coefficient of 15ppm/°C. This specific part number denotes the SO8 package variant with a ±1% initial accuracy tolerance. It is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage reference performance
• Capacitor-free operation while maintaining stability with capacitive loads
• Small outline surface mount packaging suitable for space-constrained designs

Applications

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

Procurement Notes

Verify the component datasheet against the manufacturer's official documentation to confirm electrical characteristics and pinout configurations. Ensure that the SO8 package suffix matches the required PCB footprint. Confirm compliance with relevant environmental standards such as RoHS before final procurement decisions are made.

Selection Notes

Select this component when a precise 2.45V reference is required in a compact surface-mount form factor. The ±1% tolerance offers higher precision compared to standard 3% variants. Consider the operating current limits and thermal dissipation capabilities relative to the specific application environment.

Part Context

This component belongs to the ZRA245 series of precision voltage references produced by Diodes Incorporated. The series includes various package options including SOT23, TO92, and SO8. The N8 suffix specifically identifies the SO8 small outline package configuration, distinguishing it from through-hole or smaller surface-mount alternatives within the same functional family.

Replacement Considerations

Compatible substitutes include other ZRA245 series parts with different tolerances or packages, such as ZRA245F01 (SOT23) or ZRA245R01 (TO92). Verify pin compatibility and thermal requirements when substituting across package types.
