Product details

100 mA shunt regulator with ±1% accuracy

The internal 2.495 V bandgap reference sets the programmable output floor; external resistor dividers scale the output up to 36 V. The 700 µA minimum cathode current keeps the device biased in its linear region across the load range.

Industrial temperature grade and SOT-323-6L footprint

The SOT-323-6L package (also listed as 6-TSSOP/SC-88/SOT-363) occupies roughly 2.1 mm × 2.1 mm board area. At 100 mA cathode current, the package dissipation is about 350 mW; the copper pad area under the device sets the effective thermal resistance, so keep the ground-plane connection generous.

Active lifecycle, sourced per BOM quantity

No official successor or second-source cross-reference is listed; the TL431 family is broadly second-sourced across multiple manufacturers, but this exact suffix variant should be qualified against the BOM position.

Frequently asked questions

What is the datasheet and pinout of TL431AICT?

Design engineers need the full specifications and pin configuration to validate fit in their circuit.

Where can I buy TL431AICT and what is the current stock and price?

Sourcing buyers need real-time availability and pricing to fill BOM lines without delays.

Is TL431AICT a drop-in replacement for TL431A?

Buyers and techs need to confirm compatibility when substituting common obsolete or alternative part numbers.

What is the difference between TL431AICT and TL431AIDT?

Engineers need to distinguish between SOT-363 and SOIC packages for PCB layout decisions.

Is TL431AICT obsolete or end of life (EOL)?

Brokers and buyers need lifecycle status to avoid supply chain disruptions or to plan last-time buys.

What is the output current and voltage accuracy of TL431AICT?

Designers must verify the reference can meet their circuit's accuracy and drive requirements.
