Overview
The TL431BIDBZR,215 is a three-terminal shunt regulator from the Nexperia TL431 family. It provides a programmable output voltage ranging from Vref = 2.495 V to 36 V, configured via two external resistors. This specific variant belongs to the B-Grade category, offering a reference voltage tolerance of 0.5%. It operates within an ambient temperature range of -40 °C to 85 °C and utilizes normal pinning configuration in a SOT-23 surface-mount package.
Feature Summary
- Programmable output voltage up to 36 V
- High precision with 0.5% reference voltage tolerance
- Qualified for automotive applications under AEC-Q100 Grade 1 standards
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. Ensure the selected grade matches the required thermal operating range of -40 °C to 85 °C for the target application environment. Cross-reference the part number with the latest longevity program data to confirm availability status.
Selection Notes
Select this component when high accuracy is required, specifically where a 0.5% reference voltage tolerance is necessary compared to standard or A-grade alternatives. The -40 °C to 85 °C operating range makes it suitable for industrial environments that do not require the extended -40 °C to 125 °C range offered by the Q-series variants.
Part Context
This device is part of the broader TL431 shunt regulator family manufactured by Nexperia. It shares functional similarities with other variants like the TL431AQDBZR but differs in reference voltage tolerance and specified operating temperature range. The component serves as a precise voltage reference and control element in power management systems.
Replacement Considerations
Direct substitutes include TL431BCDBZR,215 and TL431BMFDT, provided the lower 0°C to 70°C operating range of the BCDBZR variant is acceptable for the design.
