AS431AZ-E1

Overview

The AS431AZ-E1 is an adjustable precision shunt voltage reference manufactured by Diodes Incorporated. It operates within a cathode-to-anode voltage range of 2.5V to 36V and supports a maximum output current of 100mA. The device features an initial accuracy tolerance of ±0.5% and a standard temperature coefficient of 20ppm/°C. Designed for through-hole mounting, it utilizes the TO-92 (TO-226AA) package. The component functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

Provides stable adjustable voltage reference via shunt regulation topology
Maintains high initial accuracy with low temperature drift characteristics
Supports wide input voltage range suitable for diverse power supply architectures

Applications

Precision voltage references in analog signal conditioning circuits
Programmable power supply feedback loops
Battery-operated equipment requiring stable reference voltages

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with existing thermal management requirements given the operational temperature limits. Confirm RoHS compliance status for environmental regulations relevant to the target deployment region.

Selection Notes

Select this component when a through-hole adjustable shunt regulator is required with ±0.5% initial accuracy. Consider the TO-92 package constraints for board space and thermal dissipation. Evaluate the 100mA current capability against load requirements to ensure adequate headroom for regulation stability under varying conditions.

Part Context

This part belongs to the AS431 series of adjustable precision shunt regulators from Diodes Incorporated. It serves as a cost-effective alternative to Zener diodes in applications demanding higher stability and lower temperature coefficients. The series is widely utilized in industrial and consumer electronics for voltage monitoring and reference generation tasks.
