Overview
The TL431CZ is a programmable shunt voltage reference from the TL431 series by STMicroelectronics. It provides an adjustable output voltage ranging from 2.495 V to 36 V using two external resistors. The device features an initial accuracy of ±2% and operates within a temperature range of 0°C to +70°C. It supports a cathode current range of 1 mA to 100 mA with a typical dynamic impedance of 0.2 Ω. The component utilizes a TO-92-3 through-hole package.
Feature Summary
- Adjustable output voltage capability between 2.5 V and 36 V via external resistors
- Guaranteed temperature stability across the operating range
- Wide sink current capability from 1 mA to 100 mA
Applications
- Precision voltage regulation in power supplies
- Optocoupler driver circuits
- Programmable Zener diodes
- Voltage monitoring systems
Procurement Notes
Verify that the specific order matches the TL431CZ designation, ensuring the ±2% tolerance and TO-92-3 package are confirmed. Check for AEC-Q100 qualification requirements if automotive standards apply, as this specific suffix may differ from extended temperature variants. Confirm RoHS compliance status with the supplier prior to finalizing procurement documentation.
Selection Notes
Select the TL431CZ when a standard 2.5 V reference point with ±2% precision is required for general-purpose applications. Ensure the operating environment stays within the 0°C to +70°C range. Consider higher precision or extended temperature variants if the application demands tighter tolerances or operation below freezing temperatures.
Part Context
The TL431CZ belongs to the widely adopted TL431 family of adjustable shunt references. This series serves as a versatile alternative to traditional Zener diodes, offering superior performance characteristics including lower dynamic impedance and better thermal stability. The component is categorized under PMIC - Voltage References.
Replacement Considerations
Direct substitutes include the TL431CLP from Texas Instruments. Similar alternatives available in the market are the LT1431CZ#PBF from Analog Devices Inc. and the TL431AILP from Texas Instruments.
