Overview
The AZ431AZ-AE1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides an output voltage programmable from 2.5V to 36V with a reference voltage of 2.5V and a maximum cathode voltage rating of 40V. The device features a typical temperature coefficient of 20PPM/°C and operates within a temperature range of -40°C to +125°C. Packaged in TO-92, it supports a sink current capacity ranging from 1mA to 100mA.
Feature Summary
- Programmable precise output voltage capability spanning from the internal reference level up to the maximum rated cathode voltage.
- Guaranteed thermal stability over the full operating temperature range with low equivalent temperature deviation.
- High stability under capacitive load conditions ensuring reliable regulation without oscillation.
- Low dynamic output impedance providing stable performance across varying load currents.
Applications
- Charger circuits
- Voltage adapters
- Switching power supplies
- Graphic cards
- Precision voltage references
Procurement Notes
Verify the specific package type and tolerance when ordering, as the AZ431 series includes multiple variants such as SOT23 and SOT89 packages with different voltage tolerances. Confirm RoHS compliance status and check for any End-of-Life notifications or alternative part recommendations provided by the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a through-hole TO-92 package is required for adjustable shunt regulation. Ensure the application demands a voltage range between 2.5V and 36V and can accommodate the specified sink current limits. Consider the thermal resistance characteristics if high power dissipation is expected in the design environment.
Part Context
This part belongs to the AZ431-A family of adjustable precision shunt regulators designed to replace Zener diodes in various applications. The series offers sharp turn-on characteristics and low output noise. The AZ431AZ-AE1 specifically denotes the TO-92 package variant with 0.4% voltage tolerance and lead-free construction.
Replacement Considerations
Check for updated Green molding compound versions like AZ431AZ-ATRG1 if halogen-free requirements are necessary. Verify pinout compatibility if substituting with other TO-92 shunt regulators, as pin assignments may vary between manufacturers.
