TL431IDBZR,215

Overview

The TL431IDBZR,215 is a three-terminal shunt regulator from the TL431 series manufactured by Nexperia. It features an adjustable output voltage range between Vref and 36 V, set by two external resistors. The device offers a reference voltage tolerance of ±2% (Standard Grade) and operates within an ambient temperature range of -40 °C to 85 °C. Key electrical specifications include a typical temperature drift of 9 mV (0 °C to 70 °C), low output noise, a typical output impedance of 0.2 Ω, and a sink current capability ranging from 1 mA to 100 mA. It is housed in a surface-mount SOT-23 package.

Feature Summary

Programmable output voltage up to 36 V via external resistors
AEC-Q100 qualified for automotive reliability
Low output noise and high stability

Applications

Shunt regulator circuits
Precision current limiter designs
Isolated feedback loops for Switch Mode Power Supplies (SMPS)

Procurement Notes

Verify the specific grade suffix 'I' corresponds to the Standard Grade with ±2% tolerance and the -40 °C to 85 °C operating temperature range. Confirm the SOT-23 package type and pinning configuration matches the design requirements. Ensure compatibility with AEC-Q100 Grade 1 standards if used in automotive contexts. Cross-reference the manufacturer part number TL431IDBZR,215 with official Nexperia documentation to confirm current production status and longevity program details.

Selection Notes

Select this component when a standard-grade precision shunt regulator is required for industrial or consumer applications. The -40 °C to 85 °C temperature range suits general-purpose environments. Choose this variant over higher grades if cost efficiency is prioritized while maintaining basic precision. Verify that the 100 mA sink current capability meets the circuit's load requirements.

Part Context

This device belongs to the widely adopted TL431 family of programmable zener diodes. It serves as a direct replacement for legacy discrete Zener diodes in many linear and switching power supply topologies. The SOT-23 packaging allows for compact PCB layouts in modern electronics. Nexperia continues this lineage following its separation from NXP Semiconductor.
