Product details

Adjustable shunt reference from 2.495 V to 36 V

Rated for 100 mA continuous output current with a minimum cathode current of 700 µA. The ±1% initial tolerance is the standard precision grade — tight enough for most SMPS feedback and general-purpose biasing, though a 0.5% or 0.1% grade would be chosen for metrology or data-acquisition rails. The SOT-23-5 footprint (SC-74A case code) is a widely used, compact land pattern that fits many existing layouts without a board spin.

Package and mounting — SOT-23-5

Surface-mount in a SOT-23-5 (SC-74A) package.

Product status is Active. ROHS3 compliant.

Frequently asked questions

What are the typical cathode current and temperature drift of TL431AIDBVT?

The minimum cathode current is 700 µA, and the maximum continuous output current is 100 mA. The operating temperature range is -40°C to 85°C, which defines the drift envelope over temperature.

Is TL431AIDBVT pin compatible with TL431AIDBZR?

Both parts share the same base product number (TL431) and the same SOT-23-5 footprint. Pin compatibility is standard across the TL431A family in the same package, though always confirm the marking code against the datasheet for the specific tolerance grade.

What is TL431AIDBVT's listed tolerance?

The initial tolerance is ±1%.
