ZR40401R41STOB

Overview

The ZR40401R41STOB is a precision micropower shunt voltage reference providing a nominal output of 4.096 V with an initial accuracy of ±1%. 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) three-pin package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage regulation 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 official Diodes Incorporated 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 packaging is required alongside precision voltage referencing. The low minimum operating current of 60 µA makes it suitable for battery-powered designs where quiescent consumption must be minimized. Verify that the load current requirements fall within the 60 µA to 15 mA recommended operating range for optimal performance.
