Overview
The AZ431AN-BTRG1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of VREF to 18V and supports a sink current capacity from 1mA to 100mA. The device features a typical reference voltage deviation of 4.5mV and a full-range temperature coefficient of 20PPM/°C. It offers an initial voltage tolerance of 0.4% and maintains stability under capacitive loads. The component functions reliably across an ambient temperature range of -40°C to +125°C.
Feature Summary
- Programmable precise output voltage ranging from 2.5V to 18V
- Guaranteed thermal stability over the full operating temperature range
- Low equivalent full-range temperature coefficient for high accuracy
- Capable of sinking current from 1mA to 100mA
Applications

Procurement Notes
Verify that the specific suffix 'B' corresponds to the 0.4% voltage tolerance variant as defined in the manufacturer's ordering information table. Confirm the package type matches the required application constraints, as the AZ431-B series is available in multiple form factors including SOT-23, SOT-23-5, SOT-89, and TO-92. Ensure compliance with RoHS standards if specified by the project requirements.
Selection Notes
Select this component when a low-cost, adjustable shunt regulator is needed to replace Zener diodes in switching power supply designs. The 0.4% tolerance option provides higher precision than standard variants. Consider the maximum cathode voltage limit of 18V when designing feedback networks. The wide operating temperature range makes it suitable for industrial or automotive environments where thermal stability is critical.
Part Context
This part belongs to the AZ431-B series of adjustable precision shunt regulators. The series includes variants with different voltage tolerances (0.4% and 0.8%) and maximum cathode voltages (20V for the B-series). The AZ431 family is designed to offer sharp turn-on characteristics and low output impedance, serving as a direct substitute for traditional Zener diodes in various regulation applications.
