AZ431LAZ-E1

Overview

The AZ431LAZ-E1 is a three-terminal adjustable shunt voltage reference manufactured by Diodes Incorporated. It operates within an output voltage range of 1.24 V to 18 V with an initial accuracy of 0.5%. The device features a temperature coefficient of 20 PPM/°C and supports a maximum cathode current of 100 mA. It functions with a minimum operating current of 100 uA and withstands input voltages up to 18 V. The component is designed for surface mount installation in TO-92 packages, ensuring thermal stability across an operating temperature range from -40°C to +125°C.

Feature Summary

Provides precise adjustable shunt regulation with high accuracy over a wide voltage range
Maintains thermal stability with low temperature coefficient characteristics
Offers robust performance with defined minimum and maximum current limits

Applications

Precision voltage reference circuits requiring adjustable output
Linear and switching power supply feedback loops
Portable equipment battery monitoring systems

Procurement Notes

Verify the specific package variant and suffix codes against official Diodes Incorporated documentation before procurement. Confirm RoHS compliance status and environmental certifications required for your assembly process. Ensure that the ordering information matches the exact electrical specifications needed for your design implementation.

Selection Notes

Select this component when a compact, adjustable shunt reference is required for space-constrained designs. Consider the 0.5% initial accuracy and 20 PPM/°C temperature coefficient for applications demanding stable reference voltages. Evaluate the TO-92 package suitability against your board layout constraints and thermal management requirements.

Part Context

This part belongs to the AZ431 series of three-terminal shunt voltage references. It serves as a direct replacement for traditional Zener diodes in many regulator applications. The series is widely used in power management ICs and general-purpose electronic circuits where reliable voltage referencing is critical for system stability and performance.
