Overview
The TL431ACDBZR,215 is a three-terminal shunt adjustable precision reference manufactured by Nexperia. It operates within an output voltage range of 2.495 V to 36 V, set via two external resistors. The device features a standard reference voltage tolerance of 2% and supports a maximum sink current of 100 mA with a typical output impedance of 0.2 Ω. It is housed in a surface-mount SOT-23 package and functions reliably across an ambient temperature range of 0°C to 70°C.
Feature Summary
- Programmable cathode voltage up to 36 V using external resistors
- Low output noise characteristics for stable regulation
- High current sinking capability from 1 mA to 100 mA
Applications
- Shunt regulator circuits
- Precision current limiter designs
- Isolated feedback loops for Switch Mode Power Supplies (SMPS)
Procurement Notes
Verify the specific suffix '215' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with the latest datasheet revision history to confirm pinout consistency and material composition changes.
Selection Notes
Select this component when a 2% initial accuracy is sufficient for the application's voltage reference needs. It is suitable for industrial environments operating between 0°C and 70°C. For applications requiring wider temperature ranges or tighter tolerances, consider the A-grade or B-grade variants within the TL431 family instead.
Part Context
This device belongs to the TL431 family of programmable shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior performance in terms of dynamic impedance and temperature stability. The SOT-23 package allows for compact PCB layouts in modern consumer and industrial electronics.
Replacement Considerations
Compatible substitutes include TL431CDBZR,215 for standard grade performance and TL431AQDBZR,215 for automotive-grade reliability. Other equivalents within the family include TL431IDBZR for extended temperature ranges.
