AZ431BN-ATRE1

Overview

The AZ431BN-ATRE1 is a three-terminal adjustable precision shunt regulator from the AZ431-A series, manufactured by Diodes Incorporated. It provides a programmable output voltage ranging from 2.5V to 36V with an initial accuracy of ±0.8%. The device features a typical temperature coefficient of 20ppm/°C and supports a cathode current range from 1mA to 100mA. It operates within an ambient temperature range of -40°C to +125°C and is housed in a surface-mount SOT-23 package.

Feature Summary

Programmable precise output voltage settable between 2.5V and 36V
Guaranteed thermal stability over the full operating temperature range
Low equivalent full-range temperature coefficient for high stability
Sharp turn-on characteristics suitable as a Zener diode substitute

Applications

Charger circuits
Voltage adapters
Switching power supplies
Graphic cards
Precision voltage references

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer procurement. Confirm RoHS compliance status and specific packaging details such as tape and reel quantities against official Diodes Incorporated documentation prior to ordering. Ensure design compatibility with the specified SOT-23 footprint and electrical parameters.

Selection Notes

Select this variant when an 0.8% voltage tolerance is sufficient for the application requirements. Consider the AZ431AN-ATRE1 if tighter 0.4% accuracy is needed. Verify that the maximum cathode voltage rating of 36V aligns with the system supply rails. Ensure the load capacitance remains within stable operating boundaries defined in the datasheet performance characteristics.

Part Context

This component belongs to the AZ431-A family of adjustable precision shunt regulators. It serves as a direct replacement for traditional Zener diodes in various power management applications. The series offers multiple package options including TO-92, SOT-89, and SOT-23, catering to diverse board space and thermal dissipation needs across consumer and industrial electronics.
