AZ431AR-ATRE1

Overview

The AZ431AR-ATRE1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides an output voltage programmable from 2.5V to 36V with a typical reference voltage of 2.5V and a tolerance of ±0.4%. The device operates within a cathode current range of 1mA to 100mA and features a low temperature coefficient of 20ppm/°C. It is housed in a SOT89 surface-mount package and supports an operating ambient temperature range from -40°C to +125°C.

Feature Summary

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

Applications

Switching power supplies
Chargers
Voltage adapters
Graphic cards
Precision voltage references

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific packaging details against the manufacturer's official documentation. Ensure the selected variant matches the required voltage tolerance and package type for the intended application design.

Selection Notes

Select this component when a stable, adjustable reference voltage is required in compact designs. The SOT89 package offers distinct thermal and footprint advantages compared to smaller alternatives. Verify that the load capacitance remains within stability boundaries to prevent oscillation during operation.

Part Context

This part belongs to the AZ431-A series of adjustable precision shunt regulators. The 'A' suffix indicates a maximum cathode voltage rating of 40V, while the 'R' suffix specifies the SOT89 package configuration. The 'ATRE1' designation denotes the tape and reel packaging format compliant with lead-free standards.
