AZ432ARTR-E1

Overview

The AZ432ARTR-E1 is a low voltage three-terminal adjustable precision shunt regulator from the Diodes Incorporated AZ432 series. It operates within a cathode voltage range of VREF to 18V and supports a continuous cathode current from 0.1mA to 100mA. The device provides an internal reference voltage of 1.25V with a typical temperature deviation of 3mV and a full-range temperature coefficient of 20PPM/°C. It features a dynamic output impedance of 0.05Ω and functions across an ambient temperature range of -40°C to +125°C. This component is housed in the SOT-89 package.

Feature Summary

Provides sharp turn-on characteristics and guaranteed thermal stability over the full operating range.
Offers high stability under capacitive load conditions for reliable regulation.
Features low equivalent full-range temperature coefficient and low dynamic output resistance.
Capable of high sink current capacity ranging from 0.1mA to 100mA.

Applications

Graphic cards
PC motherboards
Voltage adapters
Switching power supplies
Chargers

Procurement Notes

Verify that the specific part number AZ432ARTR-E1 matches the required SOT-89 package and RoHS compliance status. Confirm the voltage tolerance specification aligns with design requirements, as the series offers distinct accuracy grades. Ensure procurement channels are authorized, as the manufacturer explicitly states no liability for products purchased through unauthorized sales channels.

Selection Notes

Select this component when a low-voltage adjustable shunt regulator is needed to replace Zener diodes in switching power supplies or chargers. Consider the SOT-89 package for its physical dimensions and thermal properties. Verify that the application circuit can maintain the minimum cathode current of 0.1mA for proper regulation and does not exceed the maximum cathode voltage of 18V.

Part Context

The AZ432ARTR-E1 belongs to the AZ432 series of low voltage three-terminal adjustable regulators manufactured by Diodes Incorporated. These ICs are designed as ideal substitutes for Zener diodes in various electronic applications requiring precise voltage referencing and regulation capabilities.

Replacement Considerations

The datasheet explicitly states: PART OBSOLETE - USE AZ431L. Designers should transition to the AZ431L series as the recommended replacement for this discontinued product.
