ZRC330F01TC

Overview

The ZRC330F01TC is a precision micropower voltage reference from Diodes Incorporated, utilizing a bandgap circuit design to deliver a stable 3.3V output. It operates within an industrial temperature range of -40°C to +85°C and requires no external stabilizing capacitor. The device supports an operating current between 20µA and 5mA, with a typical knee current of 15µA. It features a ±1% initial accuracy tolerance and a maximum temperature coefficient of 50ppm/°C. The component is housed in a compact SOT-23 package.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external capacitors
• Low knee current characteristic enables efficient operation in battery-powered applications
• Rugged design withstands transient effects and currents up to 200mA
• Superior switching capability allows the device to reach stable operating conditions rapidly

Applications

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

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'TA' for tape-and-reel packaging. Confirm that the requested part number corresponds to the correct reel size and quantity specifications defined by Diodes Incorporated. Ensure compatibility with surface-mount assembly processes suitable for the SOT-23 package dimensions.

Selection Notes

Select this component when space-saving is critical due to its small outline SOT-23 package. It is suitable for low-power designs requiring a precise 3.3V reference with minimal quiescent current consumption. Consider the ±1% tolerance and 50ppm/°C temperature coefficient for applications demanding high accuracy over the industrial temperature range.

Part Context

The ZRC330 series includes variants with different tolerances, such as ±2% and ±3%. The F01 designation specifically indicates the 1% tolerance version. Other package options like E-Line are obsolete, making the SOT-23 variant the primary choice for new designs requiring this specific voltage reference performance.

Replacement Considerations

Direct substitutes include other ZRC330 variants with matching voltage but potentially different tolerances (e.g., ZRC330F02TA for 2%, ZRC330F03TA for 3%). Verify pinout compatibility and ensure the alternative meets the required operating current and temperature specifications.
