AJZ432ANTR-E1

Overview

The AJZ432ANTR-E1 is a three-terminal shunt adjustable voltage reference from Diodes Incorporated, housed in an SOT-23 package. It provides a programmable output voltage range of 1.25V to 18V. The device features an initial accuracy tolerance of 0.5% and a typical temperature coefficient of 20 PPM/°C. It supports a maximum cathode current of 100 mA and operates within a wide temperature range from -40°C to +125°C. The component serves as a low-cost alternative to Zener diodes with high stability under capacitive loads.

Feature Summary

• Provides precise shunt regulation with adjustable output voltage via external resistors
• Ensures thermal stability across the entire operating temperature range
• Offers low dynamic output resistance for improved load regulation
• Capable of driving high sink currents up to 100 mA

Applications

• Graphics cards

Procurement Notes

Verify that the specific part number AJZ432ANTR-E1 matches the required 0.5% accuracy grade and SOT-23-3 surface mount package configuration. Confirm compliance with RoHS standards and check for any manufacturer production change notifications or end-of-life status updates prior to finalizing procurement orders.

Selection Notes

Select this component when a low-profile, adjustable shunt reference is needed for space-constrained designs. Ensure the application requires an output voltage between 1.25V and 18V and can accommodate the specified 20 PPM/°C temperature drift. Verify that the circuit design supports the minimum cathode current requirements for stable operation.

Part Context

This component belongs to the AZ432 series of low-voltage three-terminal adjustable regulators. It is designed to replace traditional Zener diodes in applications requiring higher precision and better temperature stability. The series includes variants with different accuracy grades and packaging options to suit various industrial and consumer electronics needs.

Replacement Considerations

Public confirmed substitute part numbers include AZ432ANTR-G1 and AZ432BNTR-E1. Note that these substitutes may differ in accuracy tolerance or manufacturing status; verify electrical specifications against the original requirements before substitution.
