ZR431N8TA

Overview

The ZR431N8TA is an adjustable precision shunt regulator manufactured by Diodes Incorporated, housed in an SO-8 surface-mount package. It provides a reference voltage of 2.5V with 2% tolerance and a maximum temperature coefficient of 55 ppm/°C. The device supports cathode voltages up to 20V and offers current sink capability ranging from 50µA to 100mA. Operating temperatures span from -40°C to +85°C.

Feature Summary

Temperature compensated for operation over the full specified range
Programmable output voltage via external divider resistors
Low output noise characteristics

Applications

Shunt regulator circuits
Series regulator configurations
Voltage monitoring systems
Over voltage or under voltage protection
Switch mode power supplies

Procurement Notes

Verify the specific suffix N8 confirms the SO-8 package configuration before procurement. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure design compatibility with the 20V absolute maximum rating and 100mA current handling limits. Check for any recent product change notices affecting pinout or electrical specifications.

Selection Notes

Select this component when a low-noise, temperature-compensated shunt regulator is required in an SO-8 footprint. It serves as a direct replacement for standard zener diodes where improved stability and programmability are needed. Consider the 2% initial accuracy and 55 ppm/°C drift for precision applications requiring stable reference thresholds.

Part Context

This part belongs to the ZR431 family of three-terminal adjustable shunt regulators. The N8 suffix specifically denotes the SO-8 surface-mount package variant. The family includes other packages like TO-92, SOT-23, and SOT-223 with varying tolerance options such as 1% and 0.5%.
