TS3431IZ

Overview

The TS3431IZ is a programmable shunt voltage reference manufactured by STMicroelectronics, housed in a TO-92 plastic package. It provides an adjustable output voltage ranging from 1.24 V to 24 V using an external resistor bridge. The device features a reference input voltage of 1.24 V with ±2% precision at 25°C and operates within an industrial temperature range of -40°C to +125°C. It supports a cathode operating current between 0.5 mA and 100 mA, with a maximum cathode-to-anode voltage of 25 V.

Feature Summary

Adjustable output voltage settable between 1.24 V and 24 V via external resistors
Guaranteed temperature stability across the full industrial operating range
High sink current capability supporting loads up to 100 mA
Performance compatible with industry standard TL431

Applications

Computers
Instrumentation
Battery chargers
Switch mode power supply
Battery operated equipments

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package type matches design requirements as variants exist. Check for parameter-equivalent active replacements if long-term supply continuity is required. Ensure compliance with RoHS directives before integration into final products.

Selection Notes

Select this component when space-saving surface mount alternatives are not mandatory and through-hole mounting is preferred. Consider the ±2% initial accuracy sufficient for general-purpose regulation tasks. Evaluate thermal dissipation capabilities within the TO-92 package constraints under maximum load conditions.

Part Context

The TS3431 belongs to the TS3431 family of programmable shunt voltage references. This series includes variants with different precision levels and packaging options, such as SOT23-3L. The TS3431IZ specifically denotes the TO-92 bulk packaged version with standard precision tolerance.
