ZRB500F01TA

Overview

The ZRB500F01TA is a precision micropower shunt voltage reference from Diodes Incorporated, delivering a fixed output of 5.0V with an initial accuracy of ±1%. It operates within a recommended current range of 50µA to 15mA and features a typical temperature coefficient of 15ppm/°C. The device withstands transient effects up to 200mA and reaches stable operating conditions in under 10µs. It functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Capable of withstanding transient currents up to 200mA for rugged performance
• Achieves stable operating conditions in less than 10 microseconds
• Utilizes green molding compound free of bromine and antimony

Applications

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

Procurement Notes

Verify the specific tolerance suffix (F01) corresponds to the required ±1% accuracy during procurement. Confirm the SOT-23-3 package orientation matches the schematic pinout. Ensure the application circuit maintains the minimum operating current of 50µA to guarantee regulation stability. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when high precision is required alongside low power consumption. The ±1% tolerance makes it suitable for applications demanding strict voltage accuracy. Consider the small SOT-23-3 package size for space-constrained designs. Evaluate the 15ppm/°C temperature coefficient against environmental thermal variations to ensure long-term stability requirements are met.

Part Context

This part belongs to the ZRB500 series of precision 5V micro-power voltage references. The 'F' suffix indicates the SOT-23 surface-mount package, while '01' specifies the 1% tolerance variant. Other variants include 2% and 3% tolerances, as well as through-hole packages like E-Line and SO-8, though many legacy through-hole options are obsolete.

Replacement Considerations

Obsolete through-hole variants such as ZRB500N802TC and ZRB500R03STOB can be replaced by the SOT-23 version. Verify that the replacement accommodates the necessary current handling and physical footprint constraints of the existing design.

FAQ

Does the ZRB500F01TA require an external capacitor for stability?

No, the device design provides a stable voltage without an external capacitor and remains stable even with capacitive loads.

What is the maximum transient current the device can withstand?

While the recommended operating current is up to 15mA, the rugged design allows the reference to withstand transient currents up to 200mA.
