AZ432BZTR-G1

Overview

The AZ432BZTR-G1 is a discontinued low voltage adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of VREF to 18V and supports a continuous cathode current from 0.1mA to 100mA. The device provides an internal reference voltage of 1.25V with a 1.0% tolerance, resulting in an output range of 1.24V to 18V when configured with external resistors. It features a typical temperature coefficient of 20PPM/°C and dynamic impedance of 0.05Ω. The component is housed in a TO-92 package with ammo packing and functions across an operating ambient temperature range of -40°C to +125°C.

Feature Summary

Provides sharp turn-on characteristics and guaranteed thermal stability over the full operating temperature range.
Features low equivalent full-range temperature deviation and low dynamic output resistance for stable regulation.
Offers high stability under capacitive load conditions suitable for demanding power supply environments.

Applications

Switching power supplies
PC motherboards
Graphic cards

Procurement Notes

This part number is officially obsolete and has been discontinued by the manufacturer. Sourcing new units directly from authorized channels is not possible. Buyers must verify the authenticity of any available surplus stock through independent testing. Procurement should focus on identifying verified replacement components that meet the original electrical specifications and pinout requirements.

Selection Notes

Designers requiring this functionality should evaluate the AZ431L series as the designated replacement. The AZ431L maintains similar adjustable shunt regulator capabilities while ensuring continued manufacturing support. Selection criteria should prioritize matching the required voltage tolerance, package type, and operating temperature range to ensure seamless integration into existing circuit designs without modification.

Part Context

The AZ432 series serves as a low-voltage alternative to traditional Zener diodes, offering superior precision and stability. This specific model belongs to the broader family of three-terminal adjustable regulators designed for applications requiring precise voltage referencing. The transition to the AZ431L series represents the manufacturer's strategy to consolidate product lines while maintaining performance standards for power management ICs.
