Overview
The AZ432AZTR-G1 is a discontinued low-voltage three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides a programmable output voltage ranging from 1.25V to 18V using two external resistors. The device features guaranteed thermal stability across an operating temperature range of -40°C to +125°C, with a typical full-range temperature coefficient of 20PPM/°C and a reference voltage tolerance of ±0.5%. It operates within a cathode current range of 0.1mA to 100mA and utilizes the SOT-23 surface-mount package.
Feature Summary
- Provides sharp turn-on characteristics and low dynamic output impedance for stable regulation
- Ensures high stability under capacitive load conditions
- Features low output noise and low equivalent full-range temperature deviation
- Functions as a precise substitute for Zener diodes in adjustable regulator circuits
Applications
- Switching power supplies
- PC motherboards
- Graphic cards
- Voltage adapters
- Chargers
Procurement Notes
This component is officially obsolete and has been discontinued by the manufacturer. Verify end-of-life status through official Diodes Incorporated channels before design finalization. Confirm that replacement components meet all required electrical specifications and pinout compatibility for existing layouts.
Selection Notes
Select this part only if legacy designs specifically require the AZ432 series characteristics. Evaluate alternative available components such as the AZ431L series for new implementations. Ensure the selected replacement maintains the necessary voltage tolerance and package dimensions for the target application.
Part Context
The AZ432 series belongs to Diodes Incorporated's portfolio of low-voltage adjustable precision shunt regulators. These devices are designed to replace traditional Zener diodes, offering superior performance metrics including lower temperature coefficients and higher sink current capacity. The series supports multiple package options including TO-92, SOT-23, SOT-23-5, and SOT-89.
Replacement Considerations
Diodes Incorporated recommends the AZ431L series as the official replacement for the discontinued AZ432 products. Verify functional equivalence regarding voltage ranges and package types when transitioning to the recommended substitute.
FAQ
What is the maximum cathode voltage rating for the AZ432?
The absolute maximum cathode voltage rating is 20V, while the recommended operating cathode voltage extends up to 18V.
How is the output voltage determined for this regulator?
The output voltage is set to any value between 1.25V and 18V using two external resistors connected to the reference pin.
