TL431ILPRE

Overview

The TL431ILPRE is a three-terminal programmable shunt regulator diode manufactured by onsemi. It operates as a low temperature coefficient Zener diode, with an adjustable output voltage range from 2.5 V to 36 V. The device supports a cathode current range of 1.0 mA to 100 mA and features a typical dynamic impedance of 0.22 Ω. It utilizes a TO-92-3 package for through-hole mounting and functions as a precise voltage reference in various electronic circuits.

Feature Summary

Three-terminal programmable shunt regulator design
Low temperature coefficient operation
Wide operating current capability
Low dynamic output impedance

Applications

Digital voltmeters
Power supplies
Op amp circuitry

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments also produces the TL431ILPRE variant. Confirm that the specific part number matches the intended source before procurement. Ensure compatibility with existing circuit designs regarding pinout and thermal characteristics. Check for any recent product change notices or end-of-life announcements associated with this specific component revision.

Selection Notes

Select this component when a stable, adjustable voltage reference is required in a through-hole configuration. The wide current range allows flexibility in biasing conditions. Consider the low dynamic impedance for applications demanding high stability against load variations. Evaluate the temperature compensation requirements against the specified full-range coefficient.

Part Context

This component belongs to the TL431 family of programmable precision references. These devices are widely used as replacements for traditional Zener diodes due to their superior accuracy and temperature stability. The family includes various packages and tolerance grades to suit different industrial and consumer electronics applications.

Replacement Considerations

Direct substitutes include other TL431 variants from different manufacturers such as Texas Instruments or STMicroelectronics, provided they share the same pinout and electrical specifications. Verify equivalent dynamic impedance and temperature coefficients when cross-referencing.
