AZ431LBZTR-G1

Overview

The AZ431LBZTR-G1 is a low-voltage adjustable precision shunt regulator from the AZ431L series by Diodes Incorporated. It provides a programmable output voltage ranging from 1.24V to 18V using two external resistors. The device features a typical temperature deviation of 3mV and a full-range temperature coefficient of 20PPM/°C. It offers a dynamic output resistance of 0.05Ω typical and supports a sink current capacity between 0.1mA and 100mA. The component operates within an ambient temperature range of -40°C to +125°C and utilizes a TO-92 package with ammo packing.

Feature Summary

Provides wide programmable precise output voltage from 1.24V to 18V
Ensures high stability under capacitive load conditions
Features low equivalent full-range temperature coefficient for thermal consistency
Delivers high sink current capacity suitable for various regulation tasks

Applications

Graphic cards
PC motherboards
Voltage adapters
Switching power supplies
Chargers

Procurement Notes

Verify that the ordering suffix 'B' corresponds to the required 1.0% voltage tolerance and 'Z' indicates the TO-92 package configuration. Confirm the '-G1' suffix ensures compliance with RoHS 3 standards and halogen-free requirements. Ensure the procurement channel sources the Ammo Packing variant as specified by the TR designation in the part number structure.

Selection Notes

Select this component when a low-cost, three-terminal adjustable reference is needed to replace Zener diodes. It is suitable for applications requiring sharp turn-on characteristics and low output impedance. Consider the TO-92 package constraints regarding thermal dissipation and mounting space compared to surface-mount alternatives like SOT-23 or SOT-89.

Part Context

This part belongs to the AZ431L series of low-voltage adjustable precision shunt regulators. The series is designed to offer guaranteed thermal stability over a full operation range. It serves as a direct substitute for standard Zener diodes in precision voltage regulation circuits where stable reference voltages are critical.
