ZR40402R41

Overview

The ZR40402R41 is a precision micropower shunt voltage reference providing a nominal output of 4.1V with an initial tolerance of ±2%. Manufactured by Diodes Incorporated, it utilizes a bandgap circuit design and is housed in an E-Line (TO-92 style) three-pin package. The device operates within a recommended current range of 60µA to 15mA, ensuring stability without requiring external stabilizing capacitors. It features a typical temperature coefficient of 20ppm/°C and maintains performance across an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Bandgap circuit design provides stable voltage reference without the need for external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA 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 package suffix 'R' corresponds to the E-Line configuration when sourcing. Confirm that the component meets the required initial accuracy of 2% and temperature coefficient specifications for your application environment. Ensure the operating current remains within the 60µA to 15mA range for optimal performance. Check for any RoHS compliance documentation relevant to your region's regulations before finalizing procurement.

Selection Notes

Select this component for applications requiring a compact, low-power voltage reference where space constraints favor through-hole or TO-92 style packages over surface mount options. It is suitable for designs needing high transient immunity and fast stabilization times. Consider the ±2% tolerance if higher precision is not critical, as 1% variants are available in different package styles. Ensure the system can support the maximum reverse current limits during fault conditions.

Part Context

This part belongs to the ZR4040 series of micropower voltage references from Diodes Incorporated. The series offers various fixed voltage outputs and tolerances in both SOT23 and E-Line packages. The ZR40402R41 specifically denotes the 4.1V output with 2% tolerance in the E-Line format, serving as a robust alternative to standard transistor outlines for industrial and consumer electronics.
