ZR40401R41STZ

Overview

The ZR40401R41STZ is a precision micropower shunt voltage reference providing a nominal output of 4.096 V with 1% initial accuracy. It utilizes a bandgap circuit design and operates within a recommended current range of 60 µA to 15 mA, supporting absolute maximum currents up to 25 mA. The device features a typical temperature coefficient of 20 ppm/°C and maintains stability without external capacitors. It is housed in an E-Line (TO-92 style) package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and high currents up to 200 mA due to rugged 20-volt processing.
• Superior switching capability allows the device to reach stable operating conditions within microseconds.

Applications

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

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tolerance. Confirm availability status as distribution channels may list obsolete or end-of-life components. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when space-saving through-hole requirements are needed alongside surface-mount alternatives like SOT-23. Choose based on the required tolerance level, where '1' indicates 1% accuracy. Consider the operating current limits to ensure the bias current remains within the 60 µA to 15 mA recommended range for optimal performance.

Part Context

This part belongs to the ZR4040 series of precision voltage references manufactured by Diodes Incorporated. The series offers both SOT-23 and E-Line packages with varying tolerances. The R suffix specifically denotes the E-Line, 3-pin reversed configuration, distinguishing it from the F suffix used for SOT-23 packages.
