ZR40402F50TC

Overview

The ZR40402F50TC is a precision micropower shunt voltage reference providing a nominal output of 5.0 V with an initial accuracy of ±2%. 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 across the -40°C to +85°C range and 40 ppm/°C over the extended -55°C to +125°C range. It is housed in a compact SOT-23 surface-mount package.

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.
• Fast 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 and test equipment
• Data acquisition systems
• Precision power supplies

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tolerance. Confirm availability status as product lifecycles may change. Ensure compatibility with system thermal requirements given the SOT-23 package constraints. Cross-reference datasheet electrical characteristics for your specific ambient temperature range before finalizing procurement.

Selection Notes

Select this component when space-saving surface-mount designs require a stable 5.0 V reference. The low minimum operating current of 60 µA makes it suitable for battery-powered applications where quiescent current must be minimized. Verify that the load current remains within the 60 µA to 15 mA recommended range for optimal performance and stability.
