AZ431BZ-BTRE1

Overview

The AZ431BZ-BTRE1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of VREF to 18V and supports a continuous sink current from 1mA to 100mA. The device features a reference voltage tolerance of 0.8% and a typical temperature coefficient of 20PPM/°C. It is housed in a TO-92 package with tape and reel packaging, ensuring thermal stability across an operating ambient temperature range of -40°C to +125°C.

Feature Summary

Programmable precise output voltage ranging from 2.5V to 18V
High stability under capacitive load conditions
Low equivalent full-range temperature deviation

Applications

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

Procurement Notes

Verify the specific suffix 'BTRE1' corresponds to the TO-92 package with tape and reel packaging as defined in the ordering information table. Confirm that the 'B' designation indicates the 0.8% voltage tolerance variant. Ensure compatibility with RoHS compliance requirements specified for the E1/G1 suffix variants.

Selection Notes

Select this component when a 0.8% initial accuracy is sufficient for the application. The TO-92 package is suitable for through-hole mounting. Verify that the maximum cathode voltage requirement does not exceed 18V. Consider the low output impedance and sharp turn-on characteristics for stable regulation in switching applications.

Part Context

This part belongs to the AZ431-B series, which includes variations in packages such as SOT-23, SOT-23-5, and SOT-89. The 'B' suffix denotes the 0.8% voltage tolerance option, distinct from the 'A' suffix used for 0.4% tolerance parts. The series provides a reliable alternative to Zener diodes in adjustable regulator designs.
