ZR40402F41TC

Overview

The ZR40402F41TC is a precision micropower shunt voltage reference from Diodes Incorporated, delivering a nominal output of 4.096 V with an initial accuracy of ±2%. Housed in a compact SOT-23 surface-mount package, it operates within a recommended current range of 60 µA to 15 mA and withstands 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 functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Bandgap circuit design provides stable voltage reference 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 rapidly

Applications

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

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'F' for SOT-23 packaging. Confirm RoHS compliance status and lead times directly with Diodes Incorporated or authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required tolerance and package type before procurement.

Selection Notes

Select this component for applications requiring a precise 4.096 V reference in space-constrained designs. The SOT-23 package offers a small outline suitable for surface mount technology. Consider the ±2% tolerance and 20 ppm/°C temperature coefficient for industrial environments. Ensure the load current remains within the 60 µA to 15 mA recommended operating range for optimal performance.

Part Context

This device belongs to the ZR4040 series of micropower voltage references designed for low-power applications. The series includes variants with different output voltages and tolerances, available in both SOT-23 and TO-92 packages. The ZR4040-4.1 specifically targets the 4.1 V reference market, providing a stable alternative to traditional zener diodes in portable and battery-operated electronics.
