AZ431BN-BTRE1

Overview

The AZ431BN-BTRE1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It features a maximum cathode voltage of 20V and an output voltage range from 2.5V to 18V. The device offers a reference voltage tolerance of 0.8% with a typical temperature coefficient of 20PPM/°C. It operates within a temperature range of -40°C to +125°C, supports a sink current capacity from 1mA to 100mA, and utilizes a SOT-23 surface-mount package.

Feature Summary

Provides programmable precise output voltage between 2.5V and 18V
Ensures high stability under capacitive load conditions
Features low equivalent full-range temperature coefficient for thermal consistency

Applications

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

Procurement Notes

Verify the specific suffix 'BTRE1' corresponds to the 0.8% tolerance variant in the SOT-23 package. Confirm RoHS compliance status as indicated by the E1 or G1 designation in ordering information. Ensure the application circuit respects the absolute maximum ratings, particularly the 20V cathode voltage limit and the continuous cathode current range.

Selection Notes

Select this component when a 20V maximum cathode voltage rating is required instead of the 40V AZ431-A series. Choose the 0.8% tolerance version if cost optimization is prioritized over the tighter 0.4% accuracy. Verify that the SOT-23 package dimensions fit the PCB layout constraints and that the thermal resistance characteristics are suitable for the expected power dissipation levels.

Part Context

This part belongs to the AZ431-B series of adjustable precision shunt regulators. It serves as a direct replacement for Zener diodes in various electronic designs. The series includes variants with different voltage tolerances and package options, including TO-92, SOT-23-5, and SOT-89, allowing flexibility in thermal management and board space requirements.
