ZRC400F02TA

Overview

The ZRC400F02TA is a precision shunt voltage reference from Diodes Incorporated, providing a fixed output of 4.096 V with an initial accuracy tolerance of ±2%. It utilizes a bandgap circuit design and operates within a recommended current range of 23 μA to 5 mA. The device features a typical temperature coefficient of 30 ppm/°C and maintains stability without requiring external capacitors. It is housed in a surface-mount SOT-23 package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Bandgap circuit design for stable micropower voltage reference
• Capacitor-free operation with inherent capacitive load stability
• Low knee current characteristic for efficient battery-powered applications
• Rugged design capable of withstanding transient effects up to 200 mA

Applications

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

Procurement Notes

Verify component status before procurement as the ZRC400F02TA is listed as obsolete in official documentation. Confirm availability through authorized distributors or check for valid replacement part numbers such as the ZRC400F01TA. Ensure that any substitute components meet the required electrical specifications and package dimensions for your specific application requirements.

Selection Notes

Select this component when a precise 4.096 V reference is needed in space-constrained designs utilizing the SOT-23 package. Consider the low operating current range suitable for power-sensitive applications. Evaluate the ±2% tolerance against system requirements, noting that tighter tolerances are available in other variants within the same product family.

Part Context

This component belongs to the ZRC400 series of precision voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerance levels, such as ±1% and ±3%, all sharing the same core bandgap architecture and 4.096 V output. The F suffix indicates the SOT-23 surface-mount package configuration.

Replacement Considerations

The datasheet identifies the ZRC400F01TA as the closest alternative to obsolete E-Line variants, though it offers ±1% tolerance instead of ±2%. Verify pin compatibility and thermal characteristics when substituting.
