NCV431AIDMR2

Overview

The NCV431AIDMR2 is a programmable precision shunt regulator diode from onsemi, part of the TL431 family. It operates as a low temperature coefficient zener, adjustable from Vref to 36 V using two external resistors. The device features a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. It offers an initial accuracy of 1% and a temperature coefficient of 50 ppm/°C. Designed for automotive applications, it meets AEC-Q100 standards and functions within an ambient temperature range of -40°C to +125°C.

Feature Summary

Programmable output voltage capability up to 36 V
Temperature compensated operation across full rated range
Low dynamic output impedance for stable regulation
Automotive qualification compliant with AEC-Q100

Applications

Digital voltmeters
Power supplies
Op amp circuitry
Shunt regulators

Procurement Notes

Verify the specific suffix 'DMR2' corresponds to the Micro8 package (CASE 846A) and tape & reel shipping format. Confirm the 'NCV' prefix indicates automotive grade status and site/change control requirements. Ensure the ordering code matches the required 1% tolerance specification for the A series.

Selection Notes

Select this component when a precise, adjustable reference voltage is needed in space-constrained designs requiring the Micro8 footprint. It serves as a direct replacement for standard Zener diodes where higher accuracy and lower temperature drift are critical. Verify that the cathode current requirements fall within the 1 mA to 100 mA operational window for optimal performance.

Part Context

This device belongs to the TL431, A, B Series and NCV431A, B family of programmable precision references manufactured by onsemi. The NCV prefix specifically designates parts intended for automotive and other applications requiring strict site and change control protocols. It shares functional characteristics with the broader TL431 family while adhering to automotive reliability standards.
