TL431ACZT

Overview

The TL431ACZT is an adjustable shunt voltage reference manufactured by STMicroelectronics in a TO-92 package. It provides a reference voltage of 2.5 V with ±1% initial accuracy and operates within a temperature range of 0°C to +70°C. The device supports an output voltage setting between 2.5 V and 36 V using two external resistors, with a sink current capability ranging from 1 mA to 100 mA. It features a typical dynamic impedance of 0.22 Ω and is AEC-Q100 qualified for automotive applications.

Feature Summary

AEC-Q100 qualified for automotive environments
Adjustable output voltage settable between 2.5 V and 36 V
Wide cathode current operating range from 1 mA to 100 mA

Applications

Power supply regulation
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix 'CZT' corresponds to the TO-92 plastic package with tape and reel or ammopack delivery format as defined in the ordering information table. Confirm that the ±1% accuracy grade matches the design requirements, noting that other precision grades exist within the same family. Ensure the operating temperature range of 0°C to +70°C is sufficient for the intended application environment.

Selection Notes

Select this component when a standard 2.5 V reference with high current sinking capability is required in a through-hole package. The TO-92 form factor suits general-purpose designs where board space is not strictly constrained. Consider alternative packages like SOT23-3 or SO-8 if surface-mount technology is preferred or if extended industrial temperature ranges are necessary.

Part Context

This part belongs to the TL431/TL432 family of programmable shunt voltage references. These devices function similarly to Zener diodes but offer significantly improved performance characteristics, including lower dynamic impedance and higher current handling capabilities. The family is widely utilized across various industries for providing stable reference voltages in feedback loops.
