TLVH431NIDBZR-QR

Overview

The TLVH431NIDBZR-QR is an adjustable precision shunt regulator from the Nexperia TLVH431N-Q family, designed for automotive and commercial applications. It operates within a temperature range of -40 °C to +85 °C and features A-Grade reference voltage tolerance of 1.0%. The device allows programmable output voltages up to 14 V using two external resistors. Key electrical parameters include a cathode-anode voltage limit of 14 V, a sink current capability ranging from 0.08 mA to 70 mA, and a typical dynamic impedance of 0.1 Ω. It is qualified according to AEC-Q100 Grade 1 standards.

Feature Summary

A-Grade reference voltage tolerance of 1.0% ensures high precision regulation.
Qualified according to AEC-Q100 Grade 1 for automotive reliability.
Low output noise with a typical dynamic impedance of 0.1 Ω.
Active output circuitry provides sharp turn-on characteristics.

Applications

Shunt regulator
Precision current limiter
Precision constant current sink
Isolated feedback loop for Switch Mode Power Supply (SMPS)

Procurement Notes

Verify the specific suffix IDBZR-QR confirms the -40 °C to +85 °C operating range and 1.0% A-Grade tolerance. Confirm the SOT23 package pinning configuration matches the design requirements, as mirrored pinning variants exist within the family. Ensure compliance with AEC-Q100 Grade 1 qualification requirements for the target application environment.

Selection Notes

Select this component when a precise, low-noise shunt regulator is required for automotive environments. The A-Grade tolerance suits designs needing tighter voltage accuracy than standard grades. Verify that the maximum cathode current of 70 mA and 14 V voltage rating align with the system's power dissipation and load conditions.

Part Context

This part belongs to the TLVH431N-Q family of three-terminal shunt regulators manufactured by Nexperia. The family includes variants with different temperature ranges and tolerances, utilizing the SOT23 surface-mounted package. These devices serve as replacements for Zener diodes in on-board regulation and adjustable power supply circuits.

Replacement Considerations

Check pinning configurations carefully, as mirrored pinning versions exist within the same package type. Ensure thermal resistance values match the PCB layout constraints. Verify that the replacement maintains the required AEC-Q100 Grade 1 qualification status for automotive use.
