This device has a typical output impedance. Active output circuitry provides a very sharp turnon characteristic, making the device an excellent replacement for Zener diodes and other types of references in applications such as onboard regulation, adjustable power supplies, and switching power supplies. 1 Low Output Noise Typical Output Impedance Sink Current Capability Adjustable Output Voltage 2 Applications • • • Onboard Regulation Adjustable Power Supplies Switching Power Supplies Device Information(1) PRODUCT PACKAGE DESIGNATOR PACKAGE TL431 TD Bare die in waffle pack(2) ORDERABLE PART NUMBER PACKAGE QUANTITY TL431TDA1 400 TL431TDA2 10 (1) For all available packages, see the orderable addendum at the end of the data sheet. (2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 5 Bare Die Information DIE THICKNESS BACKSIDE FINISH BACKSIDE POTENTIAL BOND PAD METALLIZATION COMPOSITION BOND PAD THICKNESS 10.5 mils Silicon with backgrind Anode TiW/AlCu2% 1629.9 nm Bon]d Pad Coordinates in Microns DESCRIPTION PAD NUMBER X MIN Y MIN X MAX Y MAX CATHODE N/C 1 783.59 841.248 933.958 947.928 2 169.926 841.248 271.526 942.848 mountpad 3 22.86 22.86 124.46 125.222 REF 4 771.398 107.66 858.266 265.648 Submit Documentation Feedback Copyright © 2013–2014, Texas Instruments Incorporated Product Folder Links: TL431-DIE 3 PACKAGE OPTION ADDENDUM www.ti.com 4-Feb-2021 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan (2) Lead finish/ Ball material MSL Peak Temp Op Temp (°C) (3) Device Marking (4/5) (6) TL431TDA1 ACTIVE 0 400 RoHS & Green Call TI N / A for Pkg Type 25 to 25 TL431TDA2 ACTIVE 0 10 RoHS & Green Call TI N / A for Pkg Type 25 to 25 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs. LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
