ZR40401F25TC

Overview

The ZR40401F25TC is a precision micropower shunt voltage reference from Diodes Incorporated, delivering a nominal output of 2.5V with an initial accuracy of ±1%. It utilizes a bandgap circuit design and operates within a recommended current range of 60µA to 15mA. The device features a typical temperature coefficient of 30ppm/°C and a slope resistance of 0.4Ω. It is housed in a small outline SOT-23 package (suffix F) and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Bandgap circuit design providing stable voltage without requiring external stabilizing capacitors
• Capable of withstanding transient effects and currents up to 200mA due to rugged construction
• Fast switching capability allowing 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 '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.

Selection Notes

Select this component when space-saving surface mount integration is required alongside high precision. The ±1% tolerance and low temperature drift make it suitable for applications demanding accurate voltage regulation in compact designs without additional stabilization components.
