ZRC250F02TC

Overview

The ZRC250F02TC is a precision micropower voltage reference IC manufactured by Diodes Incorporated, delivering a fixed output of 2.5V. It utilizes a bandgap circuit design and operates within an industrial temperature range of -40°C to +85°C. The device features a typical temperature coefficient of 30ppm/°C and maintains stability without requiring external capacitors. Recommended operating current ranges from 20µA to 5mA, with a low knee current of 15µA typical. It offers ±2% initial accuracy tolerance and is housed in a compact SOT-23 surface-mount package.

Feature Summary

• Bandgap circuit design provides stable voltage reference without external stabilization capacitors
• Low knee current operation enables suitability for battery-powered applications
• Rugged design withstands transient effects and currents up to 200mA
• Superior switching capability ensures stable operating conditions in microseconds

Applications

• Battery powered and portable equipment
• Instrumentation
• Test equipment

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'TA' variants for SOT-23 packaging. Confirm availability status directly with Diodes Incorporated or authorized distributors, as ordering suffixes may indicate specific tape-and-reel configurations or regional manufacturing sources not explicitly detailed in general product summaries.

Selection Notes

Select this component when space-saving surface-mount solutions are required alongside precise voltage referencing. The low knee current specification makes it appropriate for low-power designs where quiescent current consumption must be minimized. Ensure the application environment remains within the specified industrial temperature range to maintain the stated accuracy and temperature coefficient performance levels.

Part Context

This part belongs to the ZRC250 series of precision voltage references from Diodes Incorporated. The series includes variants with different tolerances (±1%, ±2%, ±3%) and packages (SOT-23 and E-Line). The F suffix denotes the SOT-23 package type, while the 02 indicates the ±2% tolerance class. This family is designed for applications requiring reliable voltage regulation in compact form factors.

Replacement Considerations

For obsolete E-Line variants, the SOT-23 package is recommended as the closest alternative. Verify pinout compatibility and thermal characteristics when substituting with other shunt voltage references from different manufacturers.
