AZ431LBKTR-G1

Overview

The AZ431LBKTR-G1 is a low-voltage adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of 1.24V to 18V and supports a sink current capacity from 0.1mA to 100mA. The device features a typical temperature coefficient of 20PPM/°C and a dynamic output resistance of 0.05Ω. It is housed in a SOT-25 (SOT23-5) surface-mount package with five pins, including an exposed pad connected to the anode. The component is RoHS compliant and halogen-free.

Feature Summary

Provides wide programmable precise output voltage ranging from 1.24V to 18V using two external resistors.
Ensures high stability under capacitive loads with sharp turn-on characteristics.
Features low equivalent full-range temperature deviation and low dynamic output impedance.
Compliant with RoHS standards and manufactured using green molding compound.

Applications

Graphic cards
PC motherboards
Voltage adapters
Switching power supplies
Chargers

Procurement Notes

Verify that the specific part number matches the required voltage tolerance and package type for your design. Confirm compliance with environmental directives such as RoHS 3 and REACH if applicable to your region. Ensure the ordering suffix corresponds to the correct packing method and material specifications provided by the manufacturer.

Selection Notes

Select this component when a low-cost, adjustable reference is needed to replace Zener diodes in space-constrained designs. The SOT-25 package offers a compact footprint suitable for surface mount assembly. Consider the thermal resistance and operating temperature range when designing for high ambient environments or limited heat dissipation paths.

Part Context

This device belongs to the AZ431L series of low-voltage adjustable precision shunt regulators. The series includes variants in TO-92, SOT-23, and SOT-89 packages. The 'B' suffix indicates a 1.0% initial accuracy tolerance, while 'K' denotes the SOT-25 package. The 'G1' suffix signifies RoHS compliance and a green, halogen-free formulation.
