TS3431CIZT

Overview

The TS3431CIZT is a programmable shunt voltage reference manufactured by STMicroelectronics. It provides an adjustable output voltage ranging from 1.24 V to 24 V using an external resistor bridge. The device features a cathode operating current range of 0.5 mA to 100 mA and operates within an industrial temperature range of -40 °C to +125 °C. It is housed in a TO-92 plastic package with tape and reel packaging.

Feature Summary

Adjustable output voltage settable between 1.24 V and 24 V via external resistors
Guaranteed temperature stability across the full operating range
High sink current capability up to 100 mA
Space-saving surface mount or through-hole compatible packages

Applications

Computers
Instrumentation
Battery chargers
Switch mode power supplies
Battery operated equipment

Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the TO-92 tape and reel packaging aligns with automated assembly requirements. Ensure design parameters remain within absolute maximum ratings, specifically the 25 V cathode-to-anode voltage limit and thermal dissipation constraints for the specific package variant.

Selection Notes

Select this component when a precise, adjustable voltage reference is required in space-constrained designs. The TS3431CIZT offers performance compatibility with industry standard TL431 devices. Consider the ±0.25% precision level at 25 °C for applications demanding high initial accuracy. Verify that the operating current requirements fall within the 0.5 mA to 100 mA range for stable regulation.

Part Context

The TS3431 series includes variants such as TS3431ILT and TS3431CILT in SOT-23-3 packages. The TS3431CIZT specifically denotes the TO-92 package configuration with tape and reel delivery. This part belongs to a family of programmable shunt references designed for general-purpose voltage regulation tasks.
