TL431AILPRPG

Overview

The TL431AILPRPG is a three-terminal programmable shunt regulator diode manufactured by onsemi. It operates as a low temperature coefficient zener, providing a reference voltage adjustable from 2.495 V to 36 V using two external resistors. The device features a cathode current range of 1.0 mA to 100 mA and a typical dynamic impedance of 0.22 Ω. It offers a reference tolerance of ±1% at 25 °C and an equivalent full-range temperature coefficient of 50 ppm/°C. Designed for through-hole mounting, it utilizes the TO-92 (TO-226) package with bent leads.

Feature Summary

Programmable output voltage capability extending up to 36 V
Temperature compensated operation across the full rated operating temperature range
Low dynamic output impedance ensuring stable regulation performance
RoHS compliant construction that is lead-free and halogen-free

Applications

Digital voltmeters
Power supplies
Op amp circuitry

Procurement Notes

Verify component authenticity against official datasheets before integration. Confirm the specific suffix matches the required package style and tolerance grade. Check for recent product change notices regarding manufacturing site updates or material declarations. Ensure compliance with environmental regulations applicable to your region prior to final procurement.

Selection Notes

Select this component when a precision adjustable reference is needed in a through-hole configuration. The wide operating current range supports various load conditions without compromising stability. Verify that the external resistor network allows the desired voltage setting within the specified limits. Consider thermal dissipation requirements if operating near maximum current ratings.

Part Context

This part belongs to the TL431 series of programmable precision references. It serves as a direct replacement for standard Zener diodes in applications requiring higher accuracy and lower temperature drift. The device integrates internal compensation to maintain stability under varying load conditions.
