Overview
The TL431ACDCKT is a precision adjustable shunt regulator manufactured by Texas Instruments. It operates within a reference voltage range of 2.495V to 36V, featuring an initial accuracy of ±1%. The device supports a maximum cathode current of 100mA and requires a minimum operating current of 600µA. It utilizes a SC-70-6 surface-mount package with a temperature coefficient of 92 ppm/°C. The component functions effectively across a standard industrial temperature range of 0°C to 70°C.
Feature Summary
- Provides precise programmable reference voltage control for stable circuit operation
- Features sharp turn-on characteristics superior to traditional temperature-compensated Zener diodes
- Offers high accuracy with tight tolerance specifications for demanding applications
Applications
- Voltage regulation in switching power supplies
- Precision voltage references in measurement equipment
- Feedback control loops in battery management systems
Procurement Notes
Verify the specific suffix 'CKT' against official datasheets to confirm reel packaging and tape-and-reel specifications. Ensure the selected variant matches the required temperature grade and accuracy class for your design. Cross-reference the manufacturer part number with authorized distributors to confirm active status and availability. Check for any recent production changes or obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a compact surface-mount solution is required for adjustable voltage referencing. Consider the SC-70-6 package size constraints and the ±1% accuracy requirement. Evaluate the thermal performance within the 0°C to 70°C operating range. Compare against other TL431 variants if wider temperature ranges or different pin configurations are needed.
Part Context
Part of the widely adopted TL431 family of adjustable shunt regulators. This series serves as a cost-effective alternative to fixed voltage references and Zener diodes. The TL431ACDCKT specifically targets applications requiring small form factors and precise voltage control in modern electronic designs.
Replacement Considerations
Direct substitutes include STMicroelectronics TL431ACCT and TL431AICT. Verify electrical compatibility and pinout alignment before substitution. Alternative packages may require PCB layout adjustments.
