TL431AIDBZR,215

Overview

The TL431AIDBZR,215 is a three-terminal adjustable precision shunt regulator from the Nexperia TL431 family. It operates within a voltage range of 2.495 V to 36 V, set by two external resistors. The device features an initial accuracy of ±1% and a typical temperature coefficient of 92 ppm/°C. It supports a maximum cathode current of 100 mA with a minimum operating current of 400 µA. The component is housed in a surface-mount SOT-23 package (3x1mm) and is rated for operation between -40°C and +85°C. It holds AEC-Q100 Grade 1 qualification.

Feature Summary

Programmable output voltage up to 36 V via external resistors
Low output impedance of 0.2 Ω (typical)
Active output circuitry provides sharp turn-on characteristics
Qualified to AEC-Q100 automotive standards

Applications

Shunt regulators
Precision current limiters
Isolated feedback loops for Switch Mode Power Supplies (SMPS)

Procurement Notes

Verify the specific suffix '215' corresponds to the required tape-and-reel packaging configuration for automated assembly. Confirm that the A-grade tolerance meets design requirements. Ensure the SOT-23 footprint matches the PCB layout. Validate thermal performance within the specified -40°C to +85°C operational range.

Selection Notes

Select this part when precise voltage referencing is required in compact designs. The ±1% tolerance offers higher precision than standard grades. The low output impedance ensures stable regulation under varying load conditions. Consider the AEC-Q100 qualification if the application demands automotive reliability standards.

Part Context

This component 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 applications. The SOT-23 package allows for space-constrained implementations while maintaining robust electrical performance across industrial and automotive environments.
