AZ431BN-ATRG1

Overview

The AZ431BN-ATRG1 is a three-terminal adjustable precision shunt regulator from the AZ431-A series, manufactured by Diodes Incorporated. It provides an output voltage programmable between VREF (2.5V) and a maximum cathode voltage of 36V. The device features a reference voltage tolerance of 0.8%, ensuring high accuracy. It operates within a wide temperature range of -40°C to +125°C and supports a sink current capacity from 1mA to 100mA. Packaged in SOT-23-3 with Tape & Reel delivery, it serves as a stable voltage reference.

Feature Summary

Programmable precise output voltage ranging from 2.5V to 36V
High stability under capacitive load conditions
Low equivalent full-range temperature coefficient
Wide operating ambient temperature range

Applications

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

Procurement Notes

Verify that the specific part number matches the required 0.8% voltage tolerance and SOT-23 package configuration. Confirm RoHS compliance and Green molding compound status if environmental restrictions apply. Ensure the supplier provides genuine Diodes Incorporated products to avoid counterfeit components. Check for any specific handling requirements related to the tape and reel packaging format during assembly.

Selection Notes

Select this component when a low-cost, adjustable shunt regulator is needed to replace Zener diodes. It is suitable for applications requiring sharp turn-on characteristics and low output impedance. Consider the 0.8% tolerance if tighter precision is not critical. Evaluate thermal resistance and power dissipation limits based on the expected cathode current and ambient temperature conditions.

Part Context

This device belongs to the AZ431-A family of adjustable precision shunt regulators. It shares functional similarities with other variants like the AZ431AN but differs in voltage tolerance specifications. The series is designed to offer thermal stability and low temperature deviation, making it a versatile alternative to traditional discrete Zener diodes in various power management and reference applications.

Replacement Considerations

AZ431BN-ATRE1 is listed as a previous generation variant with identical electrical specifications but different packing. No direct cross-manufacturer substitutes are confirmed in the provided documentation.
