AS431BZTR-E1

Overview

The AS431BZTR-E1 is an adjustable precision shunt regulator manufactured by Diodes Incorporated. It operates within a cathode voltage range of 2.5V to 36V and features a 1.0% initial accuracy tolerance. The device provides a typical temperature coefficient of 20PPM/°C and supports a sink current capacity from 1mA to 100mA. It utilizes a TO-92 package with Ammo packing and is designed for through-hole mounting. The component functions reliably across an operating ambient temperature range of -40°C to +125°C.

Feature Summary

Programmable precise output voltage ranging from 2.5V to 36V
High stability under capacitive load conditions
Low equivalent full-range temperature coefficient
Sink current capacity spanning from 1mA to 100mA

Applications

Charger
Voltage Adapter
Switching Power Supply
Graphic Card
Precision Voltage Reference

Procurement Notes

Verify the specific ordering suffix E1 confirms RoHS compliance and lead-free status as defined by the manufacturer. Confirm that the TO-92 Ammo packing variant matches the required assembly method. Ensure the 1.0% voltage tolerance designation aligns with circuit requirements. Cross-reference the datasheet revision to confirm pinout consistency for the three-terminal configuration.

Selection Notes

Select this component when a through-hole adjustable shunt regulator is required for power supply feedback loops or reference applications. The TO-92 package facilitates manual soldering or wave soldering processes. Verify that the maximum cathode voltage rating of 36V accommodates the highest expected system potential. Consider the thermal resistance characteristics if high continuous sink currents are anticipated in enclosed environments.

Part Context

This part belongs to the AS431 family of adjustable precision shunt regulators, serving as a direct replacement for Zener diodes in various regulation circuits. The series offers multiple package options including SOT23, SOT25, and SOT89, alongside the TO-92 through-hole variant. The B suffix indicates a 1.0% voltage tolerance, distinguishing it from the A suffix which denotes 0.5% tolerance.
