ZR40401R50

Overview

The ZR40401R50 is a precision micropower voltage reference from Diodes Incorporated, delivering a nominal output of 5.0 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. The device features a typical temperature coefficient of 20 ppm/°C and a slope resistance of 0.33 Ω. It is housed in an E-Line (TO-92 style) package and supports an operating temperature range of -55°C to +125°C.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200 mA due to rugged 20-volt processing.
• Superior switching capability allows the device to reach stable operating conditions in less than 10 microseconds.

Applications

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

Procurement Notes

Verify the specific suffix 'R' confirms the E-Line (TO-92 style) package configuration rather than the SOT-23 variant. Confirm that the '1' designation corresponds to the 1% tolerance level required for the application. Ensure the component meets the necessary automotive temperature range specifications if deployed in harsh environments.

Selection Notes

Select this component when a fixed 5.0 V reference with high precision (1%) is required in a through-hole compatible form factor. It is suitable for low-power designs given the minimum operating current of 60 µA. Consider the wide operating temperature range (-55°C to +125°C) for industrial or automotive applications where stability under thermal stress is critical.

Part Context

This part belongs to the ZR4040 series of micropower voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerances (1% and 2%) and packages (SOT-23 and E-Line). The ZR40401R50 specifically denotes the 1% tolerance version in the E-Line package, offering a robust alternative to surface-mount options for legacy or space-flexible designs.
