ZRC330QF01TA

Overview

The ZRC330QF01TA is an automotive-compliant, low knee current shunt voltage reference providing a fixed 3.3V output with ±1% tolerance at +25°C. It utilizes a bandgap circuit design to achieve precision micropower performance without requiring an external stabilizing capacitor. The device operates within a recommended current range of 20µA to 5mA and withstands transients up to 200mA. It features a typical slope resistance of 0.6Ω and wideband noise of 75µVrms (10Hz to 10kHz). Qualified to AEC-Q100 Grade 1 standards, it supports an ambient temperature range of -40°C to +125°C in a compact SOT-23 surface-mount package.

Feature Summary

• Automotive compliant qualification supporting PPAP documentation

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm that the specific order matches the ZRC330QF01TA designation to ensure correct ±1% tolerance and automotive compliance status. Review the latest datasheet revision for any updates regarding marking codes or packaging specifications before finalizing procurement contracts.

Selection Notes

Select this component when designing circuits requiring a stable 3.3V reference in space-constrained automotive environments. The low knee current specification makes it appropriate for battery-operated systems where minimizing quiescent consumption is critical. Ensure the application load remains within the recommended operating current limits to maintain specified accuracy and stability characteristics.

Part Context

This part belongs to the ZRC330Q family of automotive-grade voltage references manufactured by Diodes Incorporated. It shares the same electrical and thermal characteristics as other variants in the series, differentiated primarily by initial voltage tolerance and package suffixes. The 'Q' suffix indicates automotive qualification, while 'F01' specifies the 1% tolerance level and SOT-23 package configuration.

Replacement Considerations

ZRC330QF02TA provides equivalent functionality with a 2% voltage tolerance.
