TL431BCDBZR,215

Overview

The TL431BCDBZR,215 is a three-terminal adjustable shunt regulator manufactured by Nexperia in the SOT-23 surface-mount package. It provides an adjustable output voltage ranging from Vref to 36V, set via two external resistors. The device features a typical output impedance of 0.2 ohms and supports a cathode current range of 1mA to 100mA. It includes enhanced stability regions requiring very low load capability. The component operates within a temperature range of -40°C to +85°C and meets AEC-Q100 Grade 1 automotive standards.

Feature Summary

Three-terminal adjustable shunt regulator with programmable output voltage up to 36V
Low output impedance for stable performance in feedback loops
Enhanced stability region allowing operation with minimal load current
Automotive-grade reliability certified under AEC-Q100 standards

Applications

Switching mode power supply (SMPS) isolation feedback loops
On-board regulation circuits
Precision current limiters
Programmable Zener diode replacements

Procurement Notes

Verify the specific suffix 'BCD' against official Nexperia documentation to confirm the exact tolerance grade and temperature range specifications. Ensure the ordering part number matches the required automotive qualification level. Confirm package dimensions align with PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact, automotive-grade shunt regulator is required for precision voltage referencing. The SOT-23 package suits space-constrained designs. Consider the 1mA to 100mA cathode current range for load driving capabilities. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This device belongs to the TL431 family of programmable shunt regulators. It serves as a direct replacement for standard Zener diodes in various linear and switching power applications. The component integrates a bandgap reference, error amplifier, and output transistor into a single monolithic structure for high accuracy and low noise performance.

Replacement Considerations

Compatible substitutes include other Nexperia TL431 variants such as TL431AIDBZR or TL431BFDT, provided they match the required tolerance and thermal specifications. Cross-brand equivalents should be evaluated for pin compatibility and electrical parameter alignment.
